Strange behavior with 'any RegexComponent'

[stefanspringer1]

Description

With the following code:

func check1(text: String, pattern1: (any RegexComponent)?, pattern2: any RegexComponent) -> Bool {
    let pattern = pattern1 ?? pattern2 // type of 'pattern' is 'any RegexComponent'
    return text.contains(pattern) // OK
}

func check2(text: String, pattern1: (any RegexComponent)?, pattern2: any RegexComponent) -> Bool {
    return text.contains(pattern1 ?? pattern2) // Compiler error: Type 'any RegexComponent' cannot conform to 'StringProtocol'
}

there is the strange compiler message Type 'any RegexComponent' cannot conform to 'StringProtocol' for the second function. It is not clear why this is the case in comparison to the first function, the second function should have not such an issue, at least the compiler message appears to be strange, as in the first function an instance of the same type is passed to String.contains.

Reproduction

Try to compile the above code.

Expected behavior

The second function should compile and work the same as the first function, at least the compiler message could be better so the behaviour does not appear as strange as it now does.
