(Whiteboard: [fingerprinting][gfx-noted][fp-triaged])

We have a permission prompt for Canvas we added in Bug 967895.  Some light testing indicates that OffscreenCanvas does not trigger the prompt.
Whiteboard: [fingerprinting] → [fingerprinting][gfx-noted]
Here is a page to reproduce this issue, https://lyuyuan92.github.io/test_canvas_on_and_off_screen.html
With gfx.offscreencanvas.enabled and privacy.resistFingerprinting set to True, Firefox allows OffscreenCanvas API call without prompting the user.
