react-router-outlet interferes with layouting / sizing of components

[Artur-]

Description of the bug

When you put a Hilla view inside a Flow main layout, you get a < react-router-outlet> element between the main layout component and the Hilla view. This affects how the view is sized, e.g. 100% view width does not work

Expected behavior

react-router-outlet should have display: contents so it is does affect layouting
