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

In file toolkit/xre/

Gets the DocShellTreeItem from a window by QueryInterfacing it into a nsIWebNavigation and from there into an nsIDocShellTreeItem.

Gets the tree-owner from there and gets the base-window for the tree owner, and gets its main widget to obtain the native window.

Called from Cocoa code here:

This is either dead code, or very likely to be chrome-only code.

Note: Ping someone on MacOS dev about this.

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