I see few of issue with the item selection when toolbar items are overflown.

1. If a visible toolbar item is selected and we select an item from overflown list, both the items get marked as selected with blue outline. But overflow icon remains grey.
2. If an item is selected and then change window size so that selected item moves to overflow list, overflow icon becomes blue. If we change the selection to another item in the overflow list, then overflow icon becomes grey. But on hovering anywhere in the window, overflow icon becomes blue again.
3. If an item is selected in the overflow list and we select an item from the visible list, selection in the overflow list remains on opening the overflow list for the first time but overflow icon becomes grey. If we open overflow list again, selection will get removed.

I'm not sure whether this issue is in the scope of this PR.
Other than these, this PR looks good to me.
