Created attachment 399334 [details] testcase ###!!! ASSERTION: Someone tried to inhibit mutation events on optgroup child removal.: 'aMutationEvent', file /Users/jruderman/central/content/html/content/src/nsHTMLOptGroupElement.cpp, line 190 This assertion was added as part of the HTML5 parser landing (rev 8b5103cb12a6), and only happens when html5.enable is true.
Created attachment 407523 [details] [diff] [review] Remove the assertion Looks like the assertion is simply bogus. Maybe I didn't think that optgroup can occur in a context like this during the parse.
