Steps to reproduce:
- Go to the demo for MenuTagMultiselectWidget (initially selected, preset options) (may need to scroll down and find this item)
- Type an invalid value into the input (i.e. a value that is not in the dropdown list)
- Press enter
Expected:
- The exact behaviour depends on other config, but at the very least the existing tags should not be affected
Actual:
- The last existing tag is removed, along with the entered text
