Add-on name has layout issues in 'Read all reviews' page

[AlexandraMoga]

Steps to reproduce:

1. Load 'All reviews' page for an add-on with a longer title (i.e. https://addons.allizom.org/en-US/firefox/addon/grammarly-spell-checker/reviews/)
2. Observe the add-on name displayed in the details section

Expected result: Add-on name is wrapped correctly

Actual result; Characters are pushed to the second row if the entire word does not fit on the first line

Notes: reproduced on all AMO servers with FF57 (Win10 and Android 7.0)
