Bug 140436 – [EFL] REGRESSION(r177302): ASSERTION FAILED: beginAnimationUpdateCount when WebInspector starts

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Platform

[Paweł Forysiuk]

Revision r177302 introduced ASSERT(m_beginAnimationUpdateCount) in Source/WebCore/page/animation/AnimationController.cpp

It makes EFL's WebInspector crash without any user input in Debug builds. Just to note this does not occur with GTK+ port build.
Here it the produced output:
