Using BoxElem to draw candlestick charts, rendering anomalies occur at the corners of individual bars, appearing as extra pigment points.

Describe the bug
Using BoxElem to draw candlestick charts, rendering anomalies occur at the corners of individual bars, appearing as extra pigment points.

To Reproduce
Steps to reproduce the behavior:
code like

use egui::{Color32, Stroke};
use egui_plot::{BoxElem, BoxPlot, BoxSpread, Plot};
/// https://github.com/mikael-nilsson-github/egui-candlestick-chart/tree/main 
pub struct App {
    value: f64,
}

impl App {
    pub fn new(_cc: &eframe::CreationContext<'_>) -> Self {
        Self {
            value: 42.0,
        }
    }
}

fn candlestick_chart(ui: &mut egui::Ui) {
    let red = Color32::from_rgb(255,0,0);
    let green = Color32::from_rgb(0,255,0);
    let data = BoxPlot::new("",vec![
        BoxElem::new(0.3, BoxSpread::new(1.5, 2.2, 2.2, 2.6, 3.1)).whisker_width(0.0).fill(green).stroke(Stroke::new(2.0, green)),
        BoxElem::new(0.6, BoxSpread::new(1.5, 2.4, 2.4, 2.8, 3.5)).whisker_width(0.0).fill(green).stroke(Stroke::new(2.0, green)),
        BoxElem::new(0.9, BoxSpread::new(1.8, 2.0, 2.4, 2.5, 2.7)).whisker_width(0.0).fill(red).stroke(Stroke::new(2.0, red)),

        BoxElem::new(1.8, BoxSpread::new(0.5, 1.5, 1.5, 1.6, 1.7)).whisker_width(0.0).fill(red).stroke(Stroke::new(2.0, red)),

        BoxElem::new(2.7, BoxSpread::new(1.9, 2.1, 2.1, 2.7, 3.5)).whisker_width(0.0).fill(red).stroke(Stroke::new(2.0, red)),
        BoxElem::new(3.0, BoxSpread::new(2.0, 2.1, 2.1, 2.9, 3.3)).whisker_width(0.0).fill(green).stroke(Stroke::new(2.0, green)),
        BoxElem::new(3.3, BoxSpread::new(2.3, 2.9, 2.9, 3.7, 4.1)).whisker_width(0.0).fill(green).stroke(Stroke::new(2.0, green)),
        BoxElem::new(3.6, BoxSpread::new(3.1, 3.4, 3.4, 4.0, 4.2)).whisker_width(0.0).fill(red).stroke(Stroke::new(2.0, red)),
    ]);

    let plot = Plot::new("candlestick chart")
        .view_aspect(2.0);

    plot.show(ui, |plot_ui| {
            plot_ui.box_plot(data);
    });
}

impl eframe::App for App {
    fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.label(format!("value = {}", self.value));
        });
        egui::Window::new("My Window").show(ctx, |ui| {
            candlestick_chart(ui);
        });
    }
}

fn main() {
    let native_options = eframe::NativeOptions::default();
    eframe::run_native(
        "candlestic chart",
        native_options,
        Box::new(|cc| Ok(Box::new(App::new(cc)))),
    );

Screenshots

Desktop (please complete the following information):

• OS: windows 10

Reproduce the provided Rust example using BoxElem and BoxPlot on Windows 10, then inspect the BoxElem/BoxPlot rendering path for how bar corners and strokes are drawn. Compare the output with the screenshots; done means the candlestick bars render without extra pigment points at their corners.
