Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

No response

Description

mat-datepicker-input input element uses aria-haspopup="dialog" but input element itself does not trigger any popup. The calendar dialog popup can be triggered only from the mat-datepicker-toggle button, which correctly has the aria-haspopup attribute.

This violates WCAG Success Criterion 4.1.2: Name, Role, Value (Level A).

Reproduction

Example link: https://material.angular.dev/components/datepicker/overview

Steps to reproduce:

• Go to the Angular Material link above (I used Chrome)
• Start the screen reader (I used VoiceOver on MacOS)
• Navigate to the first Basic Datepicker example and its input field
• Notice that it is informing that the input has dialog pop up

Expected Behavior

The input field should not have screen reader information about popup, since it is not triggering anything.

Actual Behavior
