Multiple tiled windows are not positioned correctly on first refresh

[perfah]

When starting a new application an automatic routine is to make a refresh to the layout so that the application will have the right position, padding, etc..

However, this only appears to work the second time a refresh is made given that multiple windows are present in the layout. Investigating what makes the difference the second time would likely help to solve this issue.

Expected result: Windows are positioned correctly after the first refresh.
Current situation: Windows are positioned correctly after at least the second refresh (which could be done by e.g. switching workspaces back and forth)

Steps to reproduce:

1. Start two application within the wm: rlctl runapp firefox
2. One of the windows now probably has an incorrect padding
