[External] : Re: Focus delegation API

[Michael Strauß]

> The proposal (lifted from WPF) is to provide a mechanism which would allow a Control to replace an event’s original target with itself. This is a low-cost way of making the control appear to be a black box at the event level. It would certainly have a lower cost than, say, trying to hide skin nodes from the rest of the scene graph. I’m not aware of any toolkit that even attempts that.

Shadow DOM is an example of sub-node isolation. It also has focus delegation.
