[GridDelegate] Show inline controls for active item too
Right now the inline controls only appear for hovered items. This causes two problems:
- Not touch friendly since there is no concept of hover
- It's not obvious that there are inline actions at all unless you think to hover over them (many users do not)
We can fix both of these problems with a fairly simple change: always show the inline actions for the currently active item. This fixes problem #1 (closed) by making the actions appear when a delegate is tapped, and fixes problem #2 by providing users a hint that there are hidden hover actions, and making the actions for the current item easier to see.
