Inconsistent titles pre-FPWD
The nightly of WAI ARIA is numbered 1.3, but browser-spec associates it with a 1.2 title, presumably because that's what specref knows about since it hasn't reached FPWD.
I wonder if there is a systematic fix to this situation that browser-specs should consider.
(raised from https://github.com/mdn/content/issues/7651#issuecomment-894137711)
We could set the title from the nightly version instead of from the release version, but then there would be no way to retrieve the title of the WAI-ARIA 1.2 spec, which seems strange considering that the WAI-ARIA entry in browser-specs uses the /TR URL of version 1.2 as root url (https://www.w3.org/TR/wai-aria-1.2/) and wai-aria-1.2 as shortname.
A better fix might be to introduce a title property at the nightly level.
FWIW, the title actually comes from the W3C API, not from Specref (Specref has the same info in any case since it also uses the W3C API as source)
