[fix] Don't remove newlines during parseText

Since `text` is being used as the key in `cache.get(text)` and the

cache is checked *before* newlines were removed, the cache would always

miss if the input `text` had *any* newlines.



I updated `tagRe` to match tags which contain newlines, and added an

extra test case to ensure newlines outside of tags are preserved
