Colleagues:


Reproduced below are key portions of recent email exchanges with Dominic
Mazzoni of Google, who has implemented hit region support in Chrome.


This should give us two independent hit region implementations, which we
very much need for low-vision/magnification support in Canvas.

Chrome has hit region support implemented now. You can try it by visiting
this url and clicking "Enable" next to "Enable experimental canvas
features", and then restarting Chrome.

chrome://flags/#enable-experimental-canvas-features

Do you know if anyone would be interested in helping to test our
implementation against the spec for compliance? I think we can probably
ship it if it looks like there's broad consensus and other browsers are
shipping or actively working on it.

Hi Dominic,

We found some defects with canvas hit testing over a month ago in test
cases:

https://www.w3.org/wiki/HTML/Canvas_Task_Force/CR-Test#drawFocusIfNeeded_when_a_default_path_is_provided_and_the_associated_fallback_element_is_descendant_of_the_element_with_+focus._Scroll_the_window_so_that_the_canvas_moves

See test cases 2.12 on for Chrome Canary. Were these issues fixed?
