"Animation View" tab doesn't always resize properly
Notice in the image above that the plus button is missing, when it should be showing. In fact, resizing the window does not make it re-appear. To make it appear, you have to click the "restore" button twice on the "Animation View" tab. Then it shows up properly (see image below).
This results in the same bug for us in tomviz, since we use ParaView for this widget.
Steps to reproduce:
- Delete ParaView configuration files in ~/.config to remove saved settings.
- Open ParaView.
- Click on View->Messages or View->Python Console to bring up a window at the bottom of the screen.
- Click on View->Animation to add the animation window (there should be two tabs at the bottom, one for the messages/python console and one for animation).
- Click on the animation tab. The plus button is missing, and resizing does not seem to fix it.
This bug still occurred on my latest build of master: 13f66fff
I am using Ubuntu 18.04.
