Created attachment 556167 [details] testcase ###!!! ASSERTION: potential leak, plus waste of work: 'mTableInheritedAttributes == TABLE_ATTRS_DIRTY', file content/html/content/src/nsHTMLTableElement.cpp, line 1228 + trace-refcnt reports a leaked "nsMappedAttributes" object
Using nsHTMLTableElement::SetAttr is just buggy
Yes, bug 211636 should have used Before/AfterSetAttr, not override SetAttr.
Olli, are you fixing this? Or is Bernd? Requesting tracking for the leak regression.
I don't feel comfortable with this, see https://bugzilla.mozilla.org/show_bug.cgi?id=211636#c9 >I am insecure about the changes in SetAttr and UnsetAttr
