TTS readaloud: aria-label on generic elements with overridden ARIA role, still speaks element textual content

(aria-label should take precedence, just as AT/screen readers do)

But please be aware that aria-label is not allowed for all roles, cf. the exclude list at https://w3c.github.io/aria/#aria-label. It's a common authoring error ito add aria-label attributes when they aren't allowed.

In that case, browsers should ignore aria-label when building the accessibility tree and thus AT would not have access to it. (And the reality is much more complicated still.)

Ha ha, sounds like a sweet rabbit hole. Thanks for letting us know :)

Indeed. There are a couple of JS libraries that effectively implement the accname spec. IIRC none of them are perfect, e.g. I don't think anyone tries to figure out the "true" role since browsers have no getComputedRole API (yet).
