not sure why this was limited to Mac. Trent? Elly?

Just so that other platforms didn't "regress". A TreeView on Mac has a fancy
focus ring around the whole TreeView whereas Views at the time only showed focus
on the selected node.

(Also note that on Mac a *table* view does not have a focus ring around it, but
we're not planning to roll out a toolkit-views TaskManager in the first phase of
Harmony .. although I think the device picker(s) use(s) them..)
