position:fixed escape character exploit

If you use a backslash \ in the "fixed" ( position:f\ixed ), you can bypass the position:fixed prevention and make any element fixed to the viewport.

1 person has this problem

can confirm this works (don't worry i didn't do a public post using it)

This is still a problem, bumping this as I think it has a lot of potential for harm.

this is Actually Fixed now -- the sanitization now blocks every value of `position` other than "static", "relative", "absolute", "sticky", "inherit", "initial", "revert", "revert-layer", or "unset" (case-insensitively.)
