User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36

Steps to reproduce:

Enabled hyphenation in CSS  (hyphens:auto), (lang=de but also happens with lang=en)
Used a composite word (very common in german language) like "Papilio-3bis6" which has a hyphen in the Middle and the second part starts with a number.




Actual results:

Firefox hyphenation algorithm adds an additional hyphen at the beginning of the second line. It only happens if the second part of the composite word starts with a number. 


Expected results:

Firefox should not add an additional hyphen.

Hmm, that's weird. We recently fixed a couple of other hyphenation-related issues (bug 1478574, bug 1476437) which looked a bit similar to this, and with current Nightly the behavior I see is not exactly as described -- but it's still buggy. The extra hyphen now appears at the end of the first line rather than at the beginning of the second.

This was fixed in bug 1507661.
