Orca Version
Tested with Orca 43.1 + Firefox 124.0.1
Steps to Reproduce the Problem
- Go to the official MUI documentation of the Basic Modal component https://mui.com/material-ui/react-modal/#basic-modal
- Open the CodeSandbox example in a separate window https://vfgrk6.csb.app/
- Press "Open Modal" push button to open the modal
Expected Behavior
Screenreader shall announce the title and the content of the modal
Actual Behavior
When the modal open, screenreader doesn't announce anything and remains silent
Additional information
- Same example has been tested with NVDA and it works there as expected
