Bug report: Right click on Block item in Selection Filter does not work

Version: Rhino 8.8
Description: When right-clicking on a item in the selection filter panel, it should check the one and uncheck all the others. It works on every item except Block.

I also go back to Rhino 7 to test this feature and it works well in Rhino 7, so I think it’s a bug.
