Description (last modified by Thibaud Colas)

Follow-up to ​PR #15843 / ticket #33690 – there are two issues with the theme switcher for screen reader users:

  • The label isn’t translated
  • The label doesn’t convey the button’s current state (light, dark, auto)
  • (potential issue – the SVG elements should be hidden from screen reader users if they don’t have alternative text)

This is important for partly-sighted screen reader users, who will expect the visual appearance of the button and its screen reader announcement to both convey the current state. Particularly between the user’s "auto" system theme and a forced theme.

Here is the current accessibility tree representation (Google Chrome) as a reference:

button "Toggle Light / Dark / Auto color theme"
  StaticText "Toggle Light / Dark / Auto color theme"
  img ""
    Ignored
