The expected image has a selection that doesn't match test description. The actual image has no selection.
Comment 6 Ryosuke Niwa 2019-06-21 00:41:16 PDT
Yeah, obviously. This test isn't waiting for the selection state in the UI process to be updated at all. I don't even know why we've imported these tests...
