[2.0.11] Editor - Artifacts left over after removing entities/replacing with lab tiles

[Slackie]

I don't know if this is a bug or not, but it seems like there are clouds(?) that remain on the map after removing all entities and replacing with lab tiles.

There are also some ground effects as well that you can see in the screenshot. They seem to be animations that will continue after exiting the /editor.

Repro:

1) create new map
2) /editor
3) /editor
4) surfaces tab
5) remove all entities
6) fill with lab tiles

Thanks for the report, this is not a bug.
