[Brent Fulgham]

This does not reproduce under r204037. If you believe there is still a problem, please reopen the bug and attach a revised test case.

[Renata Hodovan]

Using the attached test case the issue still seems valid in r204165 with debug EFL and GTK builds.

[Michael Catanzaro]

*** Bug 139050 has been marked as a duplicate of this bug. ***

[Lauro Moura]

As of 256319@main, I can't reproduce it in both GTK and WPE ports.
