The width of suggested titles in the link inspector is too short for practical purposes, see: http://imgur.com/cJEnn
In production wikis like en.wp this will be an issue with titles that are long and hard to disambiguate, e.g. "List of countries by GDP (nominal) per capita" vs. "List of countries by GDP (PPP) per capita", which would both be abbreviated to "List of cou...per capita".
Perhaps the dropdown could dynamically expand in a similar manner to the search box suggestions.
