fix: Ensure trending tag name is fully visible (#831)

Previously re-binding the tag's text wouldn't re-measure the layout when
the text changed. So scrolling down a longer tag could be placed in a
textview that previously held a shorter tag.

Then it was cut off and the user couldn't see what the tag was. Use
`wrap_content` so size is measured when the content changes.
