Adding multiple new tags at once clears all new tags

[StrangeOne101]

Description

When editing a series' information and adding new tags, adding multiple at once doesn't work. It seems to mostly be a clientside thing as they disappear from the UI window before you can hit save, so I don't believe they are sent to the server yet.

To Reproduce

1. Go to a book.
2. Click the edit button
3. Go to Metadata
4. Add a new tag
5. Add another new tag. See both the current tag and the tag in step 4 be deleted from the UI window

Expected behaviour

All tags are added and not cleared.
