1596316 - HTMl select dropdowns don't expose language information

Status: NEW

(Core :: Disability Access APIs, defect, P3)

Description

[James Teh [:Jamie]]

NVDA (and perhaps JAWS, but I'm not sure) don't yet support language switching for focused controls, so this is a bit tricky to test. However, users want this functionality, so screen readers will likely eventually support this.

STR (with the NVDA screen reader):

1. Open this test case:
   data:text/html,<select size="1"><option lang="de">1
2. Tab to the select element.
3. Press NVDA+control+z to open the NVDA Python Console.
4. Paste this command and press enter:
   wx.CallLater(5000, lambda: speech.speakMessage(repr(api.getFocusObject().language)))
5. Quickly (before 5 seconds elapses), alt+tab back to Firefox and press alt+downArrow to open the dropdown.
   • Expected: 5 seconds after you pressed enter in the console, NVDA should say "de"
   • Actual: NVDA says "en_US"

This works as expected for a select element with size > 2; i.e. no dropdown. The problem is that select dropdowns are rendered in the parent process and we don't push the lang attribute for options to the parent process.
