We've had a long standing style bug where the edit icons on the summary

and description fields would show an underline under the field-required

asterisk when they were hovered over. This wasn't a problem for the

owner field because we have a special rule for the

review-request-details table that prevents hover underlines for all

links.
This change adds a rule for edit icons to prevent underlines on hover.

Hovered over the edit icon for the summary and description fields and no

longer saw blue underlines under the red asterisks.
