Doesn't preserve original source for a multiline expression with comments

$ cat test.js

(y1 >= t && y1 <= b) || // Top edge touching\n\

$ nodejs test.js
false

Run the reproducer in test.js with nodejs and compare the original code with recast.print(recast.parse(code)).code. Then inspect the parse and print path exposed through main; done means this multiline expression, including its comments and formatting, prints exactly as input and the comparison reports true.
