No more rounded corners after 2024.4.0

[Morenus77]

My Home Assistant version: 2024.4.1

Layout-card version (FROM BROWSER CONSOLE): 2.4.5

What I am doing:
grid-template-columns: 30% 30% 40%
margin: 4px
grid-template-areas: |
“left right”

What I expected to happen: keep rounded corners of all mushroom cards

What happened instead: no more rounded corners since 2024.4.0

Minimal steps to reproduce: mushroom cards or other cards with rounded borders, then include them in a grid template like this:

The least ammount of code possible to reproduce my error

grid-template-columns: 30% 30% 40%
margin: 4px
grid-template-areas: |
“left right”

End of code

This is not about mushrooms & probably happens in Panel view only.
