This might only be a problem in the demo if we've turned off event firing during initial loading (I haven't checked that this is the case)

Another weird similar behavior on undo deletion.
Reproduction steps

1. Go to the demo
2. Add some blocks to the workspace.
3. Right click and delete a (or all) block.
4. Right click on workspace and choose 'undo'
5. Observe there is no highlight.

However if you move one of blocks a little, highlight is back.
