At a guess, we're now flushing frames at some point when things don't work happily for some reason....

(In reply to comment #5) > At a guess, we're now flushing frames at some point when things don't work > happily for some reason.... Could that be the flush added in that patch? ;-)
Well, that addition is what the guess was based on, yes.
The flush leads to a nested nsTextEditorState::PrepareEditor which protects against that (added in bug 577518). http://mxr.mozilla.org/mozilla-central/source/content/html/content/src/nsTextEditorState.cpp#1161
It's the script runner at the end that restores the selection state that causes it. Would it be safe to allow that part to nest?

Would it be safe to allow that part to nest? No. Is the problem solved by adding a script blocker inside RestoreSelectionState::Run before calling AddRange?

Comment on attachment 520492 [details] [diff] [review] fix v2, with reftest The code change looks good, but please add a comment on why the script blocker is necessary. I don't think you need the spellcheck="false" in the test, though. Please remove it.

Also, it would be great if you could move the reftest to layout/reftests/editor, which would make it easier for me to run this reftest on editor changes (since it's really about the editor).
Added a code comment, removed the @spellcheck, and moved the tests to layout/reftests/editor FTR, that spellcheck=false thing is to avoid misspelled word underlines which used to be added asynchronously (at least on some platforms) which could cause oranges in reftests. I'll just have to spell correctly for tests to pass now I guess... :-) Fixed in Cedar: http://hg.mozilla.org/projects/cedar/rev/974a47b48836
