App

Thunderbird for Android

App version

8.0b3

Where did you get the app from?

Google Play

Android version

14

Device model

Pixel 5

Steps to reproduce

1. Open Thunderbird.
2. Go to settings.
3. Go to Support Thunderbird Beta
4. Turn on the TalkBack screen reader.
5. Under the Secure contribution heading, swipe through the amounts.
   

Expected behavior

Only one dollar amount can be selected at a time. Therefore, the dollar amounts are effectively a radio group. To help TalkBack users know what is going on, the buttons follow the WAI-ARIA APG Radio Group Pattern by doing the following:

• The group as a whole is coded as a radiogroup and therefore announced by TalkBack as a list.
• The currently selected button is announced as "checked".

Actual behavior

• The buttons are not coded as a group, so TalkBack does not announce them as such.
• The currently selected button is announced as "disabled".
