Fix propRef of parser to pass test262 #200

Closed d01c2 closed 5 months ago

d01c2 commented 5 months ago

This PR includes:

During testing with test262, we encountered an issue where the statement "Let _rawValue_ be the String value _rawStrings_[_index_]." was not parsing correctly. To alleviate this problem, we have made modification to propRef to address this issue.
