Already outlined in the parent task, our new TagMultiselectWidget features an inputPosition: 'outline' option, where the box above acts as container box for the selected tags.
As of v0.21.0 it resembles a normal input box too closely resulting in unmet user expectations.
You can only focus in when a tag has already been added, otherwise clicking the container box results in focussing the input field below.
A close widget is the readonly TextInputWidget, which currently doesn't feature the normal progressive accent color focus outline, but #c8ccd1 and should probably be revisited in the course of this as well.
Focussing in selects the input widget's value, similar to the TagMultiselect container above.
