I think this is taking the stripHtml function too far. Keeping whitespace and at the very least line breaks can be considered a feature, although I'm not sure if it would break anything.

Maybe adding another util removeWhitespace would make sense? And then the two can be combined for the results abstract.

[tkohr]

Good point, I completely agree (although the stripHtml function is currently only used for the preview abstract). This should make things much more clear. I've adapted accordingly.

Thanks a lot @tkohr, even though it works exactly like before I believe you still improved the readability for future contributors ;)
