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

In file layout/mathml/nsMathMLmactionFrame.cpp

https://searchfox.org/mozilla-central/rev/6566d92dd46417a2f57e75c515135ebe84c9cef5/layout/mathml/nsMathMLmactionFrame.cpp#231

Called in MathML code, not super perf sensitive.

Gets DocShell->TreeOwner->BrowserChrome, and calls SetStatus on it.

Called on MouseOver and MouseOut.

MouseOver and MouesOut implies high-frequency, but MathML implies low-use rates.

Need someone more informed about the subject to make a call about what to do here.

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