This does not reproduce for me in r204037. If you believe there is still a problem here, can you please reopen the bug and provide a revised test case?

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

Seems peculiar that this would be platform dependent. When someone finds a fix I would like to understand why the platform difference exists.
