Describe the bug
In RadzenChart, column series, when the dataset 1) includes one or more negative values, and 2) a radius is set, items with value 0 are weirdly displayed as triangles (looks like the inverse of the radius is colored in below the 0 line). The same goes for values with height smaller than the radius size.

To Reproduce

  1. Create RadzenChart with ColumnSeries
  2. Add <RadzenColumnOptions Radius="X" />
  3. In the data series, include at least 1 negative value
  4. Chart displays as screenshot below

Below repo reproduces this in Blazor Server. The behavior is the same for Blazor Wasm.

Expected behavior
0 values in the dataset should be empty, not shown as triangles.
