[Reg: 6.2 beta3->6.2 beta4] Key event is wrongly passed on

Sorry that I don't have a very useful bug title yet. I still have to figure out what actually happens, but wanted this known asap. What I did:

• take a Qt Creator built with Qt 6.2 RC
• open a dummy project
• use locator to open a file

Expected: locator closes, the file opens in an editor, the focus moves there, and otherwise nothing happens

Actual: after the file opens in the editor, a new line is added to the document at the current cursor location. As if the "return" key that was used for selecting the item in locator was passed on to the editor.

It doesn't happen when using the mouse to select the item in Qt Creator, so the key event is responsible.
