Steps to Reproduce

One stack frame is not demangled:

$s11Supercharge2AXO7ElementPAAE8elements33_35EDDAA799FBB5B74D2F426690B0D99DLL3for2asSayqd__GSo28NSAccessibilityAttributeNamea_qd__mtSo7AXErrorVYKAcDRd__lFAC3AppC_AC6WindowCTgm5

The stack trace line number referes to try value(for: attribute, as: [AXUIElement].self)?.map { T($0) } ?? [] in

enum AX {}

extension AX {
	protocol Element {}
}

extension AXError: @retroactive Error {}

extension AX.Element {
	fileprivate func elements<T: AX.Element>(
		for attribute: NSAccessibility.Attribute,
		as type: T.Type
	) throws(AXError) -> [T] {
		try value(for: attribute, as: [AXUIElement].self)?.map { T($0) } ?? []
	}
}

So it could be missing handling of mangling for nested protocols or typed throws.

Expected Result

I expected the stack frames be properly demangled.

Actual Result

Stack trace: https://sindresorhus.sentry.io/share/issue/784ced2af05b481d864831afb7c66548/

This looks more like a problem with symbolication. I'm going to transfer this issue to the main repo. This could be related to getsentry/sentry#79268.

Indeed, the current swift demangler in symbolic cannot demangle this symbol. It's possible that #854 would help, but that has stalled.
