Returning an array from tooltip formatter with false value when split is enabled does not hide tooltip

[stpoa]

Expected behaviour

With enabled tooltip.split, after returning an array from tooltip formatter when one of the values is false, after hovering series one tooltip should not be visible.

example [false, ' ', ' ', ' '] // tooltip 0 should be hidden

From api:

Callback function to format the text of the tooltip. Return false to disable tooltip for a specific point on series.

Actual behaviour

Tooltip 0 shows 'false' string
