problem evaluating code with string literal using fsx

Problem

strange incorrect behaviour dependent on presence of a comment doing string operation on attached fsx ac7bug.fsx.txt file.

Steps to reproduce

If you select and evaluate the whole attached fsx.txt file, the string [] data has an empty string as its penultimate value.

If you ignore the comment and only evaluate from line 48, the expected array is made, without the empty string entry. Using triple quotes on the input avoids the error, but I think single quotes are legal too?

The whole file with comment and single quotes evaluates correctly in Rider.
