Bug 1580565 - Part 2: Delay creating nsFrameLoader in static clone until embedder has window, r=smaug Follow-up parts in this bug depend on being able to read the `nsGlobalWindow` which embeds a `nsFrameLoader` within `CreateBrowsingContext`, which is called from the `nsFrameLoader` constructor. Unfortunately, we depend on creating the `nsFrameLoader` and `BrowsingContext` before we have the window as part of the fix to bug 1577711. This patch changes `BuildNestedPrintObjects` to instead use a list of pending clones stored on the parent `Document` object, and delays creation of the `nsFrameLoader`, and thus the inner `BrowsingContext`, until after the document has an owner global. Due to the low number of automated tests for printing, I manually tested print-previewing both the reduced test case from bug 1577711, a wikipedia article, and 'data:text/html,<object data="data:text/html,hi">' to avoid regressions.
