bug(Datepicker): In multi-year view, date picker doesnt announce selected year range

[Kmaczek]

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

14.2.7

Description

Steps to reproduce:

1. Open multi year view.
   
2. Tab to previous (or next) arrow and press enter.
   
3. Observe that, displayed year range is updated, but it's not announced
4. Tab back to the year range (incorrectly announced for firefox)
   

Reproduction

Can be reproduced on documentation page: https://material.angular.io/components/datepicker/overview#accessibility with basic datepicker example (first one)
I checked it for versions 17.0.4 and 16.2.12, 15.2.9, 14.2.7 and 12.2.13

I used NVDA, Jaws, Firefox, Chrome

Expected Behavior

• Related to Repro step no. 3: Announce change of year range.
  

• Related to Repro step no. 4: Announce '1992 to 2015'

Actual Behavior

• Related to Repro step no. 3: Visual changes should be announced to the user. This doesn't happen since version 15.
  Happens for both JAWS/NVDA and Chrome/Firefox

• Related to Repro step no. 4: its announcing previous range '2016 to 2039', instead announcing '1992 to 2015' according to displayed label. This happens for Firefox only.

Environment

• Angular: 16.1.3 (any after 14)
• CDK/Material: 16.1.3 (any after 14)
• Browser(s): Chrome, Firefox
• Operating System (e.g. Windows, macOS, Ubuntu): Windows

Hello, thank you for reporting. I can reproduce on NVDA with Firefox, but not on Chrome. Triaging as a Datepicker issue.

Environment

• material.angular.io
• Windows 10 Enterprise Version 22H2
• Chrome Version 120.0.6099.199 (Official Build) (64-bit)

Hi @zarend, it doesn't happen for NVDA indeed, but I was able to reproduce below with JAWS + Chrome/Firefox.

Related to Repro step no. 3: Visual changes should be announced to the user. This doesn't happen since version 15.
Happens for both JAWS /NVDA and Chrome/Firefox

Pressed enter multiple times in this place, but year range is not announced.
