Bug 1665489 - [marionette] Wait for the expected URL when navigation starts from inside a frame. r=marionette-reviewers,maja_zf

If a click triggers a navigation in the top-browsing context from
inside a frame, the frame gets removed and as such the "Element Click"
command immediately returns. As such waiting for the navigation to
be finished has to be taken care of by the test itself.

Bug 1658042 attempted to identify keys that could only handle legacy crypto
using CryptFindCertificateKeyProvInfo. However, it appears that this API can
be incredibly slow and potentially involve network I/O. This patch reworks
the legacy crypto handling by using CryptAcquireCertificatePrivateKey with the
CRYPT_ACQUIRE_SILENT_FLAG flag to avoid showing UI at inopportune times.

Because of D90771, we need media session to notifty its status correctly in order to deactivate the controller. Therefore, when its document becomes inactive (in bfcahce), we should treat media session as inactive and notify it to `MediaStatusManager` in order to clear the active media session if needed.

In addition, add some assertions to ensure we won't modify or set any attributes on media session when its document is inactive.

Bug 1665527 - part1 : deactivate a controller only when it doesn't have controlled media and active media session. r=chunmin

Currently, we only keep controller active when it has controlled media. That strategy works well for non-media session situation because only controlled media need to listen to media keys.

However, when having media session, thing goes slightly different. When we don't have any controlled media, active media session may still listen to media keys and do the corresponding operation. Therefore, we should keep the active media session being able to receive media keys even if the controlled media has gone and deactivate a controller when it doesn't have controlled media and no active media session.

Example, play a audible media first, then press `next track`, if media session is going to play an inaudible media (which is not a controllable media, so no controlled media is existing), we still want media session to receive and handle media keys for users.

Differential Revision: https://phabricator.services.mozilla.com/D90454

test_dynamic_reflow_root_disallowal.html: in the next part, we can calculate
`min-size:auto` as the minimum of specified size and content size correctly
regardless of the value of `flex-basis`. If we do not reset the `inline-size`
(or `block-size`) to `auto`, the flex item's min-width (or min-height) will
always be its specified size (`width:10px` or `height:10px` set in
`gReflowRootCandidateStyles`), and changing `inner` to the content size from
`width:20px` to `width:40px` will have no effect.

flex-minimum-{width,height}-flex-items-005.xht: To make the flex item
resolve min-height:auto as the specified size, the content (image) size
must be larger than it. So here we change the image size to 200x200.
Google Chrome can also pass this test after this patch.

Flex item's intrinsic size can affect the content size suggestion in the
automatic minimum size resolution, so we shouldn't optimize the reflow
away. https://drafts.csswg.org/css-flexbox-1/#min-size-auto

Add `IsFlexItem()` condition to the methods to avoid set
`IMAGE_SIZECONSTRAINED` bit in `nsImageFrame::Reflow()`. So after
decoding the image and updating its intrinsic size, we'll reflow the
flex item again.

This is needed to pass

after updating specified / content size suggestion in a later part.

We use it to merge blobs, but that doesn't match the spec. Per:

  https://html.spec.whatwg.org/#the-list-of-available-images

We should key off the URI, and thus a revoked image should be able to be
reused if the request is cached. This works to allow printing revoked
blob images, which other browsers allow.

I don't see any way to make that work easily while preserving the blob
image optimization. That being said, it seems other browsers also
re-decode when creating different URLs for the same blob (see the
test-case attached to the bug), so it seems we should be able to live
without it.

This patch changes the picture cache logic to create a new slice
if it finds a primitive with an incompatible set of shared clips.

In testing, I have been unable to find any real world content that
hits this case. There is a single test case in CI that hits this
case, which confirms that a new slice is created correctly. Due
to this, it should have minimal effect on real world browsing.

The benefit of this is that we know the set of shared clips won't
change as we continue to build the scene. The follow up patch to
this can then filter out and remove shared clips from primitives
during scene building, rather than frame building.
