such a tiny code piece leads to such a big change. looking good now 👍

[codecalm]

@kevinpapst I don't know why I haven't seen this before 🫣

[kevinpapst]

Sorry for not testing earlier 😢
I guess I will post some more smaller issues about the dark mode.

I am currently implementing the changes in my "symfony tabler bundle" and in my app.
Do I have to add the data-bs-theme="dark" in the navbars or is it still navbar-dark class?

[codecalm]

Bootstrap will remove navbar-dark in next release so I unify it with Tabler

[kevinpapst]

LGTM and all test cases work now 👍
