@chromium-wpt-export-bot chromium-wpt-export-bot commented Nov 5, 2020

The check for same-origin for image files with EXIF in canvas
drawImage was crashing for SVG images because their security
origin status is not available until the image has loaded.

Change things to not check SVG images for canvas drawImage,
which is safe because the image will be checked when drawing
the SVG itself.

Add a test for various uses of images in SVG.
