Issue Description:
Due to swiftlang/swift@4e0c6f9
executing myself.intersection(other) returns other elements instead of myself if other.count is smaller or same size.
This create a big issue in case the comparison is not done on the entire object but the hash is calculated only from specific parts of the object (see a playground attached for demonstration)
myself.intersection(other) should always return only elements from the myself Set and never from other (as it does now)
Might solve the issue, but it's really unclear to me if this one was released or not.
@lorentey could you let me know if your change is fixing this issue and the scheduled release?
We tested in Xcode 13.2.1 with Swift 5.5.2 and the bug is still reproducible
