Steps to reproduce:

1. Navigate to DM Library and add multiple images with tags
   • Alternatively: Enable Auto Tagging and add multiple images
2. Assert that the images have tags
3. On the root view, select multiple images
4. Click on the Bulk Edit Tags icon
5. On the modal, select Replace > Save without typing into the Tags field

Actual result: Because no tag was entered, portal deleted the existing tags and replaced it with nothing.
