Drive-by comment, nothing to do for this PR: `checkInheritableAttr()` exists and selectany is an inheritable attribute, so I would expect this function to be called from `checkInheritableAttr()` instead of `checkAttributesAfterMerging()`. It'd be an NFC change and I suspect it applies to other attributes with their own check functionality.
