Sticky Setting actionItem state

[jarolrod]

Current behaviour

Take the About setting page for example, this is a page with multiple rows of Settings; each setting being represented by a Setting control. The Setting control is implemented to switch between different color states depending on what's happening to it at the moment (hovered, clicked, disabled, etc...). Within a Setting control, we can have an actionItem, and this actionItem will then have it's "state" tied to the parent Setting state.

It is expected that only one setting within the row would be in the HOVERED state because the mouse can only be hovered over one Setting at a time. It then follows that because a settings actionItem is tied to it's parent setting state, only one actionItem can be in a HOVERED state. But that is not the case on master if you move your mouse really quickly over all the settings. It appears that some actionItems don't get updated about their parent Setting state changing, and get stuck on an old parent state:

Expected behaviour

Only one Setting and one actionItem should be in a state that is not "filled" or "disabled".

Steps to reproduce

Quickly run your mouse over all settings.
