https://trac.webkit.org/changeset/201087 [GTK] accessibility/meter-element.html is failing
The reason the test was failing is due to lack of implementation. Also, as part of the fix, we are now exposing the aria-valuetext value which had not previously been exposed. Because aria-valuetext is used on a number of ARIA widget roles, and because meters should be accessible, this fix is desirable.
Stable-branch-compatible patch attached.
Merged in r204708. Thanks!
