### Steps to Reproduce

Opening sandbox code should show this, two lines in one graph. Lower line with 3 data points, then an interruption with a `null` data point, then the upper line with 2 data points.

Scrolling to the right (note the numbers on the x-axis) makes the third data point of the lower line disappear. Instead, a ghost line connecting the second data point of the lower line and the first data point of the upper line appears:

### Current Behavior

The ghost line appears. Apparently, all data points outside the visible range get totally ignored, even if they're data points for interrupting lines.

### Expected Behavior

Lines should stay interrupted, no ghost line appearing.

### Environment

```markdown
- OS: Debian 13
- Browser: Firefox 140 ESR
- Framework: (none)
```
