Created attachment 271926 [details] testcase Loading the testcase triggers: ###!!! ASSERTION: How'd we get a floated inline frame? The frame ctor should've dealt with this.: 'aReflowState.mStyleDisplay->mFloats == NS_STYLE_FLOAT_NONE', file mozilla/layout/generic/nsLineLayout.cpp, line 1116
(reproducible on Linux as well as Mac)
OS: Mac OS X → All
Still happens on trunk.
Also hits the other version of this assertion (added in bug 580167).
Given MathML (which suppresses floating inside itself), this assert is bogus. We could change to asserting this or a mathml ancestor, or we could just nix the assert. David, any preference?
