Issue description

I don't know what causes it exactly. It works with sprite's texture, but doesn't for TileMapLayer's TileSet (didn't test other resources). Double-clicking or pressing enter will just revert to the original resource, without even creating undo action (seems like it's canceling?).

Steps to reproduce

1. Create a TileSet Resource file
2. Add TileMapLayer
3. Try to assign the TileSet via Quick Load
