When adding Tags, the Dropdown should remove the tags being added and add them when tags are being added

Should Apply to Kogito and BC

• The ability to edit tag should also be removed, if a user wants to change a tag, he/she can remove it and add it again. Also the Edit.... option on the dropdown should be removed

UX imporvements for the future:

The tag editing window is not shown entirely. A user has to scroll down to see neewely added tags.

When you add a long tag, it is displayed outside of tag window.

Keyboard shortcuts don't work well. For example Enter to confirm the tag addition or Esc to close Tag editing window.
