Previously, the regular expression used by the compiler's ShadowDOM CSS shim to strip comments from CSS text was susceptible to [catastrophic backtracking][1], which could lead to exponential (O(2^n)) increase in complexity/execution time. More specifically, this would be triggered if the processed text contained an unterminated comment with lots of leading whitespace (i.e. `/*`, followed by lots of whitespace characters and no closing `*/`). Although such input is unlikely in real-world scenarios, this commit improves the regular expression to not be susceptible to this issue.
