Steps to reproduce:

Have either

• a HTML document with embedded SVG or
• an SVG image
  where certain nodes have text content and an xml:space="preserve" attribute.

I'd guess the same would happen for arbitrary XML documents as well.

Actual results:

While rendering honors the attribute, the DOM inspector in the developer tools always shows the text content as if xml:space="preserved" was not specified.

Expected results:

At least those nodes that have xml:space="preserve" should show the actual text content, not the normalized one. But even in the general case the normalization is dubious, as CSS could enforce white-space rendering differences via its white-space property.

Probably a duplicate of bug 878514 which has an overly specific summary.
