Support HTML Figures in Chromium (#16206)
Fixes #16137
Summary of the issue:
Figures are currently not properly announced by NVDA in browse or focus modes in Chromium.
Description of user facing changes
Figures are now reported in Chrome.
Description of development approach:
Since Chromium does not report a role of figure on <figure> elements unless the role has been added, add tests for a tag of figure on Chrome objects. Change figure searchable attributes to include the figure tag, since this is necessary to allow navigation by HTML figures in Chrome.
Known issues:
Quick navigation by figure will land on <figure> elements whose role has been set to something other than figure.
