Details

(Whiteboard: [rm-docshell-tree-item:hard])

In file dom/html/nsHTMLDocument.cpp

Uses DocShell tree to get parent item.

Some of the code around this seems to have been fixed for Fission, e.g. the following fix within the call to Document::StartDocumentLoad https://bugzilla.mozilla.org/show_bug.cgi?id=1555050

Obtains the ContentViewer from either the current DocShell or the parent DocShell.

Users of Content-Viewer are conditionalized, and lack of one won’t crash. Might lead to failures in specific tests when the docshell content-viewer is null, and its parent is out of process.

Uses content-viewer exactly twice, here:

Kannan says replacing nsIDocShellTreeItem calls should block enabling Fission in Nightly (M6).
