Describe the bug
If you use the object custom property, there are search and pointer buttons to use to select the object you want to reference. When working on a map, these work fine. But if in a tileset and using the Tile Collision Editor, the two buttons do not work. You have to manually type the ID of the object you want to use.

If there already is a value, then the search button will work, but not the pointer button.

This error appeared in Tiled 1.9 release.
