NVDA only reads the first idref in aria-errormessage #19490
Description
Brief summary
In #16411, @SaschaCowley added support for reading the aria-errormessage property. That functionality was set up to assume that if an aria-errormessage attribute contains multiple idrefs, only the first one should be respected, since ARIA 1.2 defines aria-errormessage as being a single idref (not multiple idrefs).
However, ARIA 1.3 updates aria-errormessage to allow multiple idrefs. Chromium and Gecko both already implement support for this in their accessibility object models. It'd be nice to update the new paths introduced by #16411 to support reading multiple error messages.
