The previous version in which this bug was not present was

No response

Description

When nesting input inside of the mat-chip-grid, it becomes inaccessible with the screenreader commands (when there are chips selected).

Reproduction

StackBlitz link: https://stackblitz.com/run?file=src%2Fexample%2Fchips-input-example.html
Steps to reproduce:

1. Use material chips with input, where input is nested inside of mat-chip-grid.
2. Add at least one chip.
3. Start VoiceOver and focus the form field.
4. Navigate inside the form field using VoiceOver commands (e.g. VO-Right Arrow to move to the next item)

Expected Behavior

It should be possible to focus the input element when pressing VO-Right Arrow inside the mat-chip-grid. Similar to how it is in chip-autocomplete example, when input is not inside the mat-chip-grid:

Actual Behavior

Only chips and delete buttons can be focused using VoiceOver commands.

Environment

• Angular: 19.0.5
• CDK/Material: 19.0.5
• Browser(s): Chrome
• Operating System (e.g. Windows, macOS, Ubuntu): MacOS

Hello
The same problem exists with NVDA.
Do you think it is due to the html attributes used on the component?
