overflowTop parameter behaviour & verticalLinesHeight

[McFly78]

Description

I'm working on a LineChart graph and I'm seeing some strange behaviour when I use the overflowTop parameter.
As you can see, if the value of this parameter is other than 0, the height of the vertical lines displayed using the parameter verticalLinesHeight is much higher than the area of the graph.

There is no issue for vertical lines displayed using the global parameter showVerticalLines.
However, as I would like to only display some verticals lines I can not use the global parameter showVerticalLines.

So I've tried using the verticalLinesHeight parameter to limit the height of the vertical lines, but this parameter doesn't seem to work for the vertical lines displayed using the showVerticalLine parameter.
The verticalLinesHeight parameter only seems to have an effect for vertical lines displayed with the global parameter showVerticalLines.

Is there something I am missing ?

With an overflowTop parameter other than 0 and whatever the value

Without overflowTop parameter

As a temporary workaround, in the renderSpecificVerticalLines function I added 30 to the y2 value of the SVG Line component -> y2= -xAxisThickness +30

Many thanks for your help

Steps to reproduce

<View style={{backgroundColor: '#1A3461', paddingTop:60}}>
    <LineChart
        data={
          [10, 10, 10, 10, 10, 10, 10, 50].map((v, index) => {
          
            const showVerticalLine= index%2 !=0 // To show only half of verticals lines
            
            return {
              value: v,
              showVerticalLine: showVerticalLine ? true : false,
              verticalLineColor: "red",
              verticalLineThickness:2
            }
        })
        }
        
        overflowTop={1}
  
        // Vertical lines configuration
        verticalLinesColor= "white"
        //verticalLinesHeight={180}
        showVerticalLines={true}
        
        // graph configuration
        height={180}
        spacing={40}
        hideRules
        hideYAxisText
        yAxisColor="white"
        xAxisColor="white"
        color="#0BA5A4"
        initialSpacing={0}
        backgroundColor='#1A3461'
    />
