I have a simple form field:

<mat-form-field>
  <mat-label>Some label</mat-label>
  <input matInput type="text"/>
</mat-form-field>

Default behaviour is, that after clicking onto some part of the form-field the form label is assigned different colour – class mat-focused is assigned to the mat-form-field and there is a style with CSS selector .mat-form-field.mat-focused .mat-form-field-label, which is applied and which assigns different color.

To illustrate:

I need this style not to be applied and the easiest way I can see is to prevent the class mat-focused from being assigned, in other words to prevent mat-form-field from being focused. Is that possible somehow?

Or any other suggestion?
