[GTK][WPE] Mathml asserts with invisible operators

Summary [GTK][WPE] Mathml asserts with invisible operators
Lauro Moura
Reported 2020-08-06 08:10:29 PDT
Tests: mathml/presentation/mo-invisible.html mathml/opentype/munderover-layout-resize.html Both tests asserts in the same place (although from different bases), with m_maxPrefferedLogicalWidth==0 and glyphWidth > 0. Tests passing and rendering correctly in Release, though. Unfortunately, wktesthunter shows it to start crashing somewhere in a big gab between r238072 and r257066. Would it be the case of just removing the assert?

I can't repro this locally. Is this happening locally for others or only on the bot?

(In reply to Rob Buis from comment #3) > I can't repro this locally. Is this happening locally for others or only on > the bot? I guess this depends on installed/used fonts.

In the end, the assert in question got removed, so the tests now pass.
