Prerequisites

Ionic Framework Version

  • v4.x
  • v5.x
  • v6.x
  • Nightly

Current Behavior

The toast message in not announced by screenreaders even with aria-live='assertive'.

Tested with:

  • Ionic 6.2.4
  • NVDA 2022.2.2 on Chrome and Firefox
  • JAWS 2022.2207.25 ILM on Chrome and Firefox

Expected Behavior

According to ARIA live regions spec:

aria-live="assertive" should only be used for time-sensitive/critical notifications that absolutely require the user's immediate attention. Generally, a change to an assertive live region will interrupt any announcement a screen reader is currently making. As such, it can be extremely annoying and disruptive and should only be used sparingly.

So I expect assertive toast message to be announced when toast is shown.

Steps to Reproduce

I could provide a demo app using @ionic/angular, but I need to test the toast behaviour with JAWS (with NVDA on Chrome/Firefox is not working).
