Radzen Dropdown gets behind Bootstrap Modal

I can't find ways to fix this behaviour, apparently it's happening since migrating my project to .NET 5 (not confirmed). Is there a way to fix this without the use of Radzen Dialog?

Tks!

Edit: I tried this in a fresh Blazor App without changing a line a of CSS, same result.

Hello,

I think this is related to this post:

You need to set the z-index property using the !important CSS modifier.
