loop labels don't respect scope in switch statement

Context

        Odin:    dev-2024-10:8006ba919
        OS:      Manjaro Linux, Linux 6.1.106-1-MANJARO
        CPU:     12th Gen Intel(R) Core(TM) i7-1260P
        RAM:     31806 MiB
        Backend: LLVM 14.0.6

Expected Behavior

This should work, since the outer labels are in different scopes:

ru := 'x'
	switch ru {
	case ' ', '\n':
		outer: for i in 0 ..= 10 {
			for j in 0 ..= 10 {
				if i == j {
					break outer
				}
			}
		}
	case:
		outer: for i in 0 ..= 10 {
			for j in 0 ..= 10 {
				if i == j {
					break outer
				}
			}
		}
	}

Similar to how this works, declaring an s variable in different scopes is fine:

main :: proc() {
	ru := 'x'
	switch ru {
	case ' ', '\n':
		s := "Hello"
	case:
		s := "Hello"
	}
}

Current Behavior

/home/tadeo/Desktop/test/o2/i.odin(24:3) Error: Duplicate label with the name 'outer'
