Describe the bug
MWE
Having a screen with a panel that has a GameAreaComponentRenderer attached, where the Filler Tile is set to Tile#empty() stops it from working correctly. Rebuilding the tile from scratch fixes this behaviour

To Reproduce
Steps to reproduce the behavior:

1. Create a screen
2. Add a panel or label with a GameAreaComponentRenderer whoms filler tile is set to Tile#empty
3. Fill the Game Area with a different Tile
4. See how the GameAreaComponentRenderer shows nothing

Expected behavior
Tile#empty() to not exhibit this behaviour

Screenshots
Will do if necessary
