Eclipse loses focus after switching perspectives #2839
Description
Reproduction steps:
- Start Eclipse in a new workspace.
- Set hotkeys for showing Java and Debug perspectives (Shift+Ctrl+Alt+J resp. Shift+Ctrl+Alt+D in my case). Clicking on the perspective buttons also works.
- Open Debug perspective.
- Switch to Java perspective.
- Open Console view, open Java Stack Trace page.
- Click on the text on the page, select some text with the keyboard (Shift+Left/Right Arrow).
- Switch to Debug perspective, switch back to Java perspective, observe that focus is still on the text and keyboard can be used to select text.
- Switch to Debug perspective, open some file in an editor, select text with keyboard.
- Switch to Java perspective, there is no focus anymore, hotkeys to switch perspectives don't work.
Its the same if I focus the stack traces page of the Console view in the Debug perspective, the reproduction doesn't need an editor.
But If I click on some view tab in the Debug perspective, I don't see the bug. So it doesn't seem like a generic problem with focus not being preserved properly, focus is lost in some cases.

I see this on Linux (RHEL 9.2, gtk3-3.24.31-2.el9.x86_64) with:
