Describe the bug

When clicking on the tabs, they either flicker or move on the tab bar.

I did at one point or another have them stay in the wrong place on the tab bar, which is when i gave up and went back to AppTabs.

How to reproduce

Use attached code.
Run program.
Click the second tab a whole bunch.
