The button Show Also Inherited Members blocks UI for many seconds when pressed. The processing is done in AWT thread.
This is not a problem anymore after the fix mentioned in the issue 52607. I can work with the IDE during computation of the inherited members without AWT blocking. AWT thread is blocked during this time only if I move somewhere in navigator and tooltip computation is started in AWT thread. This locks AWT thread until the computation of inherited members finishes. But this is a problem of issue 52612.
