Don't ignore tag clicks in the tooltips

Summary:
Now that we can use the metadata widgets in the tooltips, we can also
open the tags:// url if the user clicks some tag in a tooltip.

The behavior is now consistent with the metadata widget in the information panel.

Test Plan: Click a tag when the metadata tooltip shows up.
