[BUG] What should the polyfill do with disabled style/link elements?

[jgerigmeyer]

This was raised in #242 and #243.

Right now the polyfill parses and replaces a disabled style or link element. In the case of a link element, it gets replaced with a non-disabled, polyfilled version. This is clearly a bug.

One option would be to skip parsing of disabled stylesheets, but then we may want to watch and parse them if they become un-disabled?

Another option would be to parse them, but replace the link with another disabled link. This is easier to implement, and ensures that if the stylesheet is later un-disabled then the polyfilled styles would be loaded.

Closing, replaced by #246.
