According to: https://github.com/w3c/aria/issues/451
AX: WebKit is incorrectly mapping the <meter> element to progressbar. This is probably my fault.
More here: https://github.com/w3c/html-aam/issues/2
What's the verdict on the correct mappings? HTML-AAM lists nothing for your platform, and I don't know what to put in the Core-AAM for the new meter role we have in ARIA.
