Created attachment 307025 [details] testcase See testcase, I see some white-space at the right of the combobox popup, which doesn't happen on branch in this case. I guess this might be possible to fix in forms.css: http://lxr.mozilla.org/seamonkey/source/layout/style/forms.css#213
You mean the space for the scrollbar? That basically needs to be there given the reflow branch architecture. I'm pretty sure we already have a (invalid or wontfix?) bug on that.
Also happening here now: http://extra.volkskrant.nl/select/muziek/overzicht.php
I can reproduce this extra white space when e10s is disabled. But, it is fixed with e10s.
