…ection for MatAutocomplete Adds a new input for `MatAutocomplete`: `revertValueTo`. This input works with `requireSelection` and allows the developer to provide a value that should be reverted to _instead_ of `null`. One use case for this feature is to have the autocomplete revert to the _last known_ value instead of `null` with something like: `[revertValueTo]="formControl.value"` This defaults to `null` in order to maintain backwards compatibility. The use-case that led to this change is a time zone picker. If the user does not select a time zone, it will revert to either the previously selected time zone or the browser's time zone.
