Since there's a dedicated entry I assume that the indeterminate state of input elements ends up being always ignored here? In the implementation I instead had to modify the aria-checked computation, but I think this works too.

logged this bug today per the current webkit implementation that uses pseudo content to derive a name for the switch when it is not labelled - https://bugs.webkit.org/show_bug.cgi?id=270377

i'm going to wait for response on that before i make any other updates to this PR. But, definitely not a useful name with the current implementation.

related ARIA issue where maybe the custom state presented as pseudo content could be exposed in a different/better way - w3c/aria#2085 (comment)
