Description
PHP8.1 introduced native return types to native methods
and interfaces, which crashes if they are not compatible.
As a workaround the introduced `#[\ReturnTypeWillChange]`
attribute can be used to mitigate this, which has been
used to mitigate quite some issues with it.
PHPStan has released a new version which fixes a bunch of
bugs, which detects more issues in core. These will be
addressed with the dedicated PHPStan raise patch. However,
one issue cannot be solved or added to the baseline and
must be fixed beforehand. The reason is, that phpstan also
evaluates the PHPDoc return type.
