When using CSS styled mode, column series (plot type column/bar) should be affected by zones configuration.
In latest version (5.0.4) zones aren't applied for column\bar plot type when using CSS styled mode. In particular I need className attribute working for zones, so I can have extended styling possibilities.
CSS styled mode: http://jsfiddle.net/jfd8czde/. Here zone classes are missing in HTML, so styling isn't applied at all. Change series type column to line and zones are applied.
Zones className example from docs. Changing series type to column or bar results in no styling applied.
Expected behaviour JS styled mode: http://jsfiddle.net/nLyrro54/. Zones are working as expected both for column and line types, but JS styling is very limited.
Fixed #6016, zones weren't applied for point elements in styled mode.
