Oh nooees!!😢 #Bevy 0.15 breaks #UI tests.😭 Layouts are not calculated anymore in tests.
It apparently requires a different setup of the `World`, but I'm not sure how to set it up.
I've used CameraPlugin, WindowPlugin, UiPlugin etc., but it still doesn't work (works in 0.14 though).
I've seen this setup from Bevy repo, but it seems a bit too granular for me (I prefer using bunch of Plugins):
Have to look more deeply into it tomorrow.
