When you reszize the activitybar it will soon look ugly when content leaves the plasmoid and will eventually disapear. Reproducible: Always Steps to Reproduce: 1.Make the applet smaller 2.Until is looks strange 3.Keep going until it is gone Actual Results: Applet is invisible! Expected Results: The resize stops at a reasanable minimum size.
Confirmed for 4.8.80. Widget can be resized arbitrarily pushing the contents outside the widget or making them disappear completely. The widget should have a vertical and horizontal limit for the minimum size.
Fixed in commit 66a27efd6900709b4212ad5b4e7ed7386f9ae238
