@staabm There are three more errors on 7.4 if you feel like fixing it 😊

[staabm]

Tried a few different things, but only thing I can come up with is, that we need to put these errors into the PHP7.x baseline.

all-in-code changes I tried, will result in PHP8 PHPStan errors, because it does not want us to handle a possible false value (which can only happen on PHP7).

one error case could be fixed by phpstan/phpstan#13709
