What problem is this PR intended to solve?
Fixes #2355
The JRuby code for SaveContextVisitor is brittle and clearly
buggy (since this bug exists for fragment nodes but not fragments or
document nodes?), but this seems like an easy fix.
Have you included adequate test coverage?
Yes. Though I fear we still don't have enough coverage on JRuby formatting.
Does this change affect the behavior of either the C or the Java implementations?
This brings the JRuby implementation in line with the C implementation and the XHTML spec.
