LocalBoundsAndChildren not working without Visual in Children

Bug Reports
1

I have this app:

<App>
	<Panel X="40%" Y="40%" Width="20%" Height="20%" Background="#0f0" ux:Name="pan" HitTestMode="LocalBoundsAndChildren">
		<Panel X="-100%" Y="-100%" Width="300%" Height="300%" />
		<WhilePressed>
			<Change pan.Color="#000" />
		</WhilePressed>
	</Panel>
</App>

And it works if you add Background="#0000" to the child Panel. I thought that LocalBoundsAndChildren should give the bounds, even though the child has no visual.

I don’t think there is an issue here. The HitTestMode is working as intended. Perhaps you expected the LocalBounds to extend to the children, but it does not. If you want the invisible child to detect hits you must put HitTestMode="LocalBounds" on it as well. LocalBounds only ever refers to the “local” bounds: the size of the element.

Also note, you should not combine Background with Color on a panel since Color is really a shortcut to the Background. The above won’t animate correctly if you reference it two different ways.
