Expected behaviour

Null points should never be connected.

Actual behaviour

In specific circumstances (which I cannot fully pin down), points that are not within the zoomed range (i.e. not visible) are connected.

Live demo with steps to reproduce
Zoom in on the two points in Series 2 to see Series 1 connect

Product version

Development version of boost.js
Latest stable of highcharts.js

Affected browser(s)

Only tested in Chrome
