[OpenLayers-Users] Vector Layer w/ Canvas Renderer Not Respecting Other Layers

[Mike Ryan]

Following up on this, since I haven't heard anything. I've played around 
with the canvas hit detection example here:

http://dev.openlayers.org/releases/OpenLayers-2.11/examples/canvas-hit-detection.html

and did the following:

- made an overlay layer with some of features so that I could turn the 
layer on/off
- added the LayerSwitcher control to the map
- added onFeatureSelect and onFeatureUnselect events to the layers so a 
popup appears when you click on the features
- the popups appear when clicking on the visible features
- AND the popups appear when clicking on the "invisible" features in the 
overlay when it is TURNED OFF

So, is this an issue with the HTML5 Canvas element itself or the way OL 
uses it to render Vector layers?

Does turning a Canvas layer "off" via LayerSwitcher require some extra code?
