Tooltip fallback for persistent icon-only buttons

[AdamJ]

Sighted users are not given a manner in which to understand what certain icons mean (aria-label is in place for screen readers). A <Tooltip> wrapper on persistent icon-only controls would surface this information without requiring always-visible text.

ToDo

• Add a <Tooltip> wrapper on persistent icon-only controls (such as the <RotateCcw> button which is to restore changes)
