[jimczj]

Expected behaviour

When you do not set ignoreHiddenPoint value in options, Treeamap ignoreHiddenPoint default option is true.
Before click.

After click

Actual behaviour

When you do not set ignoreHiddenPoint value in options, Treeamap ignoreHiddenPoint default option is undefined.

Live demo with steps to reproduce

http://jsfiddle.net/jimczj/egegw6mv/1/

you can change the options to
series: [{ type: "treemap", ignoreHiddenPoint: true, data: [{ name: 'A', value: 1 }, { name: 'B', value: 2 }, { name: 'C', value: 3 }, { name: 'Causes Exception', value: 4 }] }],
it performs expected behaviour,but actually in doc,ignoreHiddenPoint defaults to true.

Affected browser(s)

@jimczj Thanks for reporting, in the upcoming maintenance release (5.0.8) ignoreHiddenPoint will default to true in Treemap.
