* Fix for PartialStyleSheet getting stuck in loop
Adds a clause for detecting `//` as a comment marker when working backwards through a file, preventing the parser from getting stuck when the comment starts at 1:1
* Modify change to detect start of file instead of skipping additional `/` characters now that we know the issue only occurs at offset 0.
