I think this is simply a mistake, not something intentional in a
It’s the HTML parser that’s doing the discarding of the content here.
Changing the parser to instead create a text node seems relatively
straightforward, although not trivial.

The code in question is in the file HTMLParser.cpp. The content is
skipped by calls to the function setSkipMode. The code that actually
causes the content to be discarded is the code that calls the skipMode
() function in HTMLParser.cpp and HTMLTokenizer.cpp. There are six
different call sites.
If we change <noscript>, we probably want to do the same thing for
<noembed> and <noframes>.
One of the most important aspects of fixing this bug would be to
create some good test cases. Even someone who will not fix the bug
could create the bug in bugs.webkit.org and make test cases, try the
test cases out in other browsers and make sure they pass. That person
could even make the test cases in the proper form for the LayoutTests
directory and submit a patch with the test case and the current
expected failures as a way to get the ball rolling.
