To reproduce in the standalone monkey tester https://github.com/andy-goryachev-oracle/MonkeyTest: - run the monkey tester, TableView page, select Items: 500,000 Rows option, Selection Model: Multiple Rows - cmd-A to select all - cmd-click on selected items rapidly what I see is that some clicks are ignored - the rows remain selected. <img width="1196" height="876" alt="Screenshot 2026-03-23 at 11 40 34" src="https://github.com/user-attachments/assets/49ee6795-a40b-4e91-8f79-c19ffc2cf971"; /> ------------- PR Comment: https://git.openjdk.org/jfx/pull/2100#issuecomment-4112889942
