@lunny Why is this issue blocked, should it be moved to 1.7.0?

[lunny]

This is blocked because I found the detection is not always successful. This will be replaced by #4950

[lafriks]

Oh, I did not see that there is already PR about that issue

[lunny]

@lafriks I forgot it also until @JonasFranzDEV 's comment. 🤣

[jonasfranz]

Fixed by #4950
