* always show empty line at bottom of the tag list to allow adding more tags (replaces `+` button and tab logic)
* disable delete and info buttons on empty tag
* replace deferring of tag change events and re-rendering with a simpler logic (to fix issues like #10871):
only set input field values if the rendering event was triggered by an external event, or by a change of the respective field in the raw tag editor itself
* skip delete and tag info buttons while navigating using tab: makes it more quick to get to where one typically needs to, deleting a key using the keyboard only is possible by emptying the tag's key, and advanced users are not typically using the `i` button anyway
