Screenshot nicely shows the issue
In this example for operations and configuration tab, the text in the tab header is larger than the tab size, which either results in cut of characters (ops tab) or overflowing chars (config tab).
When I hover the tabs, they auto-correct to the correct size
This especially happens when I click on a new resource in the tree.
Also clicking on e.g. a subtab on "Summary" will correctly increase the tab header width, so me may perhaps only need to call some redraw() after the right side has loaded after a load from tree.
medium, no target release
