Bug 568089

Description Karsten Thoms 2020-10-22 00:55:24 EDT

For testing I have enabled Chromium in my platform dev IDE instance. Now the IDE is hanging and waits forever that ChromiumLib.cefswt_eval returns. Not sure what's causing the method to block, but anyway the method call should not block the UI thread.

Would it be possible defer calls to ChromiumLib to a background thread with a (configurable) timeout?
