bug(MatSelect): When panel is displayed inside a SideNav, it stays opened on Escape button

### 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

Hi,

When using MatSelect inside a SideNav, if the panel is opened and we close the sideNav with the Escape button, the MatSelect panel stays opened.

I expected the same behavior like with the MatDatePicker, if the picker panel is opened, when using Escape the picker is closed first, and then using Escape again closes the sideNav.

I also provide the same sample inside a Dialog using the MatSelect and MatDatePicker and in this case, both works the same way and correctly.

The issue seems related to this one:

Thanks

Steps to reproduce:
1. Click on button to open the SideNav
2. Open the MatSelect panel
3. Click on Escape

### Expected Behavior

MatSelect should be closed with the escape button instead of the SideNav

### Actual Behavior

SideNav is closed and MatSelect panel stays visible

Commencez par la reproduction StackBlitz liée et reproduisez la séquence Escape dans les exemples SideNav, MatSelect et MatDatePicker. Comparez la façon dont MatSelect gère Escape avec le comportement du picker. Le travail est terminé lorsque le panneau MatSelect se ferme en premier et qu'un Escape ultérieur ferme la SideNav, avec une couverture du setup signalé.
