[v2] combo bar line : lines are not properly displayed

[Seb33300]

Hello,

Since the build around January 31, on "line bar combo" charts, only dots are displayed on the line chart.

You can see the issue on the combo bar line sample:

This is related to a commit that added in some performance fixes. As an immediate work around you can set your config with the showLines property. We need to update the default config to include this property

config = {
    showLines: true
};

Fixed in #1972
