[Bug] Tab disappears after re-dragging to old window
Sometimes when you re-integrate a tab you just dragged out of the "original" window back into the "original" window, the tab disappears in the tabs bar. But the tab still exists! You can still see it when you switch between tabs with [Shift]+[Tab]. That bug only appears sometimes, not always (it failed once to reproduce the bug). Here an [url=https://abload.de/img/vivaldi20160930tabsvefusw9.png]image[/url] of a non visible tab in the tabs bar on top, but still visible when you switch between them.
