Seen with ToT (03/18) on iPad in landscape orientation. Steps to reproduce: 1. Visit <https://bugs.webkit.org/attachment.cgi?id=365109&action=review> 2. Tap grey area under a file name or tap a line in the diff that is the name of a function. Nothing happens. But should reveal hyperlinks to show context lines.

Could this have something to do with hovering?
Behavior regressed in <https://trac.webkit.org/changeset/242763/> (bug #195575).
r243414 fixes it.
