Long URLs in Unicode-non-compliant user agents

Unicode recommends to break URLs at slashes, but
some browsers don’t, so we need to prevent URLs 
from expanding the reference container in mobile view, 
or from hanging out of the tooltip even on desktop.

Based on pattern, not link element, since some URLs
are not hyperlinked, while often the hyperlink text
is common language, that mustn’t be broken anywhere.
