<style> visibly inserted into XML

[kannes]

This might be the same issue as gorhill/uMatrix#85 on umatrix.

Looking at http://sourceforge.net/sitemap.xml I noticed a block of style being inserted to the rendered page:

"Visibly"? I cannot see this.

[kannes]

I have not figured out when it appears and when not. Try loading one of the URLs in that screenshot, eg sourceforge.net/sitemap-0.xml

http://i.imgur.com/nnILOMY.png

Maybe it only appears if some referring is happening or something.

I am with Opera 26.0.1656.60

[gorhill]

Ok. I guess the tag may end up being injected outside the document head sometimes. The only thing I found out on how to solve this is to look at the value of document.contentType -- a non-standard property.

[Kelnozz]

Same issue here.

@gorhill

The only thing I found out on how to solve this is to look at the value of document.contentType -- a non-standard property.

if ( !(document instanceof HTMLDocument) ) {
   return;
}

[gorhill]

That works, thanks for the tip.

Test cases for future reference:

[kannes]

Ran into another one with uMatrix, it does not seem to happen with uBlock for me: http://line-mode.cern.ch/www/hypertext/WWW/TheProject.html

This seems to be a tracking issue so I rather post it here.

µMatrix 0.8.1.3 in Chromium Version 39.0.2171.99 (64-bit).

[kannes]

Oh, actually uBlock (in Opera) inserts something too (only sometimes, I am confused...):
