Stepped line chart with null values removes two line segments instead of one

[LaurEliPar]

Description

Steps to Reproduce

1. Create a stepped line chart with a null value in the data (ex. data: [2, 4, 1, 2, 0, 2, 4, null, 2, 0])

Expected Behavior

In the case of a stepped line chart, one line segment should be removed (the one following the data point)

Actual Behavior

The horizontal line segments after and before the data point are both removed. This makes sense for a regular line chart, but not for a stepped line chart.

Screenshots

horizontal line should appear here, between 2023-07-01 and 2023-08-01
