Can't place Object Tiles when TAB-ing between opened Map files.

[UliAbo]

To Reproduce

1. Open two TMX Maps with these properties: Both files have different names, but have the identical amount and name of ObjectLayers. They also have both one same TSX file connected.
2. Select on both Maps the same ObjectLayer.
3. Open the same Object Tileset in Tileset View on both Maps.
4. Select Tool "Insert Tile" and select one Tile from TSX and place it in the Map. This works.
5. Now only press "CTRL+TAB" for jumping to the other opened TMX Map file.
6. Here, the same Tile is of course already selected (and also the same ObjectLayer is selected). But the MouseCursor preview already shows that you can't place the Tile anymore. You need to select another Tile first and go back to the one you want.
