Named Partials render with documentFragment in stringOnly state instead of expected string result

[JaneOri]

I understand this may be marked as "won't fix" or at least probably isn't a priority since there are ways to work around it and most wouldn't ever need it. I took a few swings at fixing it but didn't get far in the time I have.

How often can you reproduce it?

• [x] Always
• [ ] Sometimes
• [ ] Rarely
• [ ] Unable
• [ ] I didn’t try

Description:

Named partials (technically section renderer) produce document fragments even when stringOnly is true in the section its being rendered in (in a style tag, for example). https://github.com/canjs/can-stache/blob/b530682034cf1e59285046df5475b57ce5e5b0b1/src/mustache_core.js#L291 "res" is a documentFragment at that line when a named partial is rendered inside of style tag.

The text representation should be rendered instead.

Steps to reproduce:

Expected results:

contents of style tag should be the raw text produced by the render. (Note: "innerHTML" of the fragment produced would be incorrect in the browser because it escapes things like ">" automatically)

Actual results:

contents of the style tag is "[object DocumentFragment]"

Environment:

Software	Version

Operating system	windows 10
