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

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: https://github.com/angular/components/issues/7981

Thanks

Hi @crisbeto,

i see the fix from @Veribelll has been canceled because there is a plan for more important changes (logic into _handleOverlayKeydown) right ? Is there any issue to follow that changes ? and are they planned ?

Thanks
