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

19

Description

When using mat-form-field in filled appearance, I want to shape the border-radius. I use this token
--mdc-filled-text-field-container-shape: 4px !important;
But it only applies to the top corners and not the bottom corners because this token uses the wrong container to set radius. It sets the radius on a level where the div for hints and errors is also included.
And by that the bottom corners are not set with that token
