Expand "in" dashboard global filter to see what you're typing

Using the “in” filter condition with HA dashboards global filters, when you run out of text input space, you can’t see what you’re typing. It’s not until you press “enter” that you can see what you typed, and if you made any mistakes in typing. This makes it difficult to use this filter logic for string fields.

In this image, I am trying to add ‘Tier 3’ as another value but you can’t see it.
