When changing printers one of them could be slower than another. If you change
to a slow printer and back to an already loaded/fast printer then the slow
printer shouldn't overwrite the settings once it finally loads.

Example: Start print on PDF printer, switch to a physical printer and back to PDF. If
the physical printer had to be contacted to pull settings this operation could take
a few seconds, at which point the settings from the physical printer could overwrite
the PDF printer settings.

The browsing context group id needs to be an 64-bit integer. Otherwise
when having a browsing context created by a child process, if it goes
over INT32_MAX, parsing fails, and we end up creating a new BCG, which
can end up in the wrong process, etc.

This allows to use the feature from the context menu and is very
straight-forward.

This has the benefit of working with fission (as print from the focused
frame) and so on.

Making a checkbox on the UI on top of this is doable, but it is a lot
more complex (requires a bunch of both front-end and platform work)
because undoing this implies restoring the DOM which "print selection"
removes.

I think the context menu entry is very useful regardless of whether we
add a checkbox to undo it, and other browsers (with smaller context
menus) seem to agree.

This was only being checked on OnDonePrinting() which isn't called in

care about document viewers getting closed during print operations,
they're top level browsers that don't run script.

Not really a fan of this, but I can't think of a better alternative
really... Ideas welcome :)

The main issue is that in bug 1662975 we made window.print() not return
until the user has closed the print / print preview dialog (as it is
needed for some use cases). This matches other browsers, too.

We use an nsAutoSyncOperation here, in order not to violate the
run-to-completion invariants, which turns off micro-tasks, timers,
etc... However we'd still want promises inside mozPrintCallback to
resolve and such, which is a bit contradictory. It is really awkward to
have this behavior change based on whether we have a print callback...
