### 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

I have am having a bit of an issue with a mat-autocomplete.
I have deployed the code base from `https://stackblitz.com/run?file=src%2Fexample%2Fautocomplete-require-selection-example.html&startScript=start` to `http://resparke-indigo-backup.s3-website-ap-southeast-2.amazonaws.com/` so I can test it on my Android 13 device.
On Android 10, IOS Safari 17, 18 etc, macbook Chrome, it all works good.
But not on Android 13' Chrome.

What I can find from debugging is that when I click it sometimes doesnt select a value but just collapses the soft keyboard.

I created a recording with onclick debug output so you can see which element is clicked:

I am not sure how to debug this, because the example I am using is pure and simple and 100% from angular mat website.
I think the issues is related to the softkeyboard closing which does something with the overlay.

### Reproduction

As mentioned above, the stackblitz example is deployed on `https://app-test.resparke.com` but you would have to run it on an Android 13 tablet , Chrome, with a soft keyboard and see this issue happening

### Expected Behavior

When option is selected, I expect that selection to be recorded.

### Actual Behavior

When I open the test app on `http://resparke-indigo-backup.s3-website-ap-southeast-2.amazonaws.com/`, and I click on the formfield, the dropdown appears and the softkeyboard opens, I select option 2. The soft keyboard closes and no option is selected. When I click again on the formfield, the dropdown appears again and now I can select and option. That seems to be a consistent behaviour on Android 13/Chrome.

### Environment

- Angular: 20.3.x
- CDK/Material: 202.2.12
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Android 13
