Expected Result: A hit region is only associated with the second control and id in a hit region list. However, since there is no API to enumerate the hit region list, canvas mouse events received must have a matching id corresponding to the second region with the id matching location touched by the mouse pointer. Each hit region must must be exposed as a best fit rectangle in screen coordinates in the platform accessibility API implementation for the corresponding fallback elements.

Test file: The test file should initially set up a hit region for each fallback element using addHitRegion with an associated id and the corresponding fallback element represented by the control at load time and then call removeHitRegion on the region having the first ID. The test file should print out mouse events associated with the ids in an area outside the canvas element. An accessibility test tool must be used so that the tester can validate that the region associated with the control matches the screen location of the hit region as a best fit rectangle.

Your expected action: none
