We'd rather 'play it safe' for our selection detection (which avoids
following links if you have some text selected). This commit adds an
additional check of 'more than 1 character' to the 'isSelected' check.
This is based on the fact that it's far quicker to type the character so
why would a user select on character? This therefore caters for any
fairly large (in the scheme of things) incidential mouse moves whilst
clicking a link.
Overall this is probably overkill
