This bug introduced with #13551.

While testing the previous PR, I didn’t encounter any issues. However, when I tried to trigger the loading dialog multiple times in quick succession—such as by attempting to create new folders repeatedly—the following exception occurred.

java.lang.IllegalStateException: Must be called from main thread of fragment host at FileActivity.showLoadingDialog().
