Tooltip stuck on first data element when first series is hidden (Combo)

[nikolaifischer]

Description

On Combo Charts the Tooltip is stuck on the first column when the first series is hidden. This only happens on the first series and when the chart.type === 'line'. With chart.type ==='bar' it works correctly

Steps to Reproduce

1. Hide the first series by clicking on the series in the legend
2. Hover over any column

Expected Behavior

• Tooltip should display the information for the column that is hovered

Actual Behavior

• Tooltip is "stuck" on the first point (in this case Dec)
• Only happens on first series, if a different series is hidden it works fine
