I'm not quite certain about the mechanics of this issue. Could you clarify?
Capturing screen content from a <video> element seems to not have this problem, since <video> doesn't contain links.
I'm not sure if we can capture screen content with a canvas, but some searching seems to indicate that the tools like [html2canvas](https://html2canvas.hertzen.com/) work by rendering the DOM, so the tricks done for fooling the script there should continue to work.
It's possible that this bug belongs on the mediacapture-screen-share spec, which does capture screen content not DOM content. Should it be refiled?
