<!-- Render this element first so the input is on top. -->
<div class="mat-mdc-radio-touch-target" (click)="_onTouchTargetClick($event)"></div>
<!--
Note that we set `aria-invalid="false"` on the input, because otherwise some screen readers
will read out "required, invalid data" for each radio button that hasn't been checked.
An alternate approach is to use `aria-required` instead of `required`, however we have an
internal check which enforces that elements marked as `aria-required` also have the `required`
attribute which ends up re-introducing the issue for us.
