Document.GetElementFromPoint will return elements that have been transformed with CSS to be behind the camera, resulting in hit tests missing elements in front of the camera.
Summary: Hit testing of elements needs to only hit elements in front of the camera → Hit testing of elements must only hit elements in front of the camera
(In reply to :kip (Kearwood Gilbert) from comment #0) > Document.GetElementFromPoint will return elements that have been transformed > with CSS to be behind the camera, resulting in hit tests missing elements in > front of the camera. Correction - The API that is working incorrectly: document.elementFromPoint(x,y)
Here is an example test case for the problem: http://mozvr.github.io/cursor-target-test
Not getting correct elements from the Y offset: https://github.com/MozVR/cursor-target-test/blob/master/index.html#L138 Ideally document.elementFromPoint(0, 0) returns the correct element at viewport center.
