angular material dialog mat-dialog-actions position

I'm using Angular Material Dialog component, with mat-dialog-content and mat-dialog-actions to display a footer with action buttons.

If I set a height of the dialog (e.g 80%), the dialog-actions is weirdly higher than the default.

Here is a forked stackblitz of an official example

I just set height: 80%

const dialogRef = this.dialog.open(DialogContentExampleDialog, {  height: '80%',  width: '520px'});

Here is the result:

In my opinion that's an issue :) but what's your opinion? Is it possible to easily fix it?

Thanks!
