User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:104.0) Gecko/20100101 Firefox/104.0

Steps to reproduce:

<div role="meter"></div>
Specification: https://www.w3.org/TR/core-aam-1.2/#role-map-meter

Currently, in firefox, meter is mapped to MSAA role: ROLE_SYSTEM_PROGRESSBAR https://searchfox.org/mozilla-central/source/accessible/base/RoleMap.h#1873

This hasn't been update on chrome yet, intentionally: https://bugs.chromium.org/p/chromium/issues/detail?id=944542

We haven't changed the mapping yet for the same reason as Chrome.

Hi Jamie, should we adjust the AAMs to use ROLE_SYSTEM_PROGRESSBAR instead? Or do you think it's worth the effort to ask both NVDA and JAWS to update first, wait a couple of years, and then change our mappings?

I'm not sure if NVDA and JAWS have even been asked yet. It's hard to justify sinking time into this because it doesn't seem like anyone cares in the wild. If JAWS hasn't been asked yet, it'll still be a few years before this can be changed.

If someone has the cycles, I guess it makes sense to at least ask JAWS and NVDA whether they'll support the new role. But without real world use cases where this is actually a problem, that'll probably be a hard sell given other priorities, though it's a fairly easy change to make.

Valerie mentioned these are likely good first bugs, so I'm marking them as such. Please feel free to correct if that's not accurate.

If anyone is willing to work on this, please be aware that we are still pondering whether we actually want to change the mapping (see above comments).
