ChartKit Content Disappears on Subsequent Modal Openings (Only Title Remains)

[spiner2000]

Describe the bug

When embedding ChartKit within a modal component, the chart content fails to render correctly after the initial opening.
First render works as expected, but subsequent renders fail to fully mount the chart.

2. Close the modal.
3. Reopen the modal.
4. Observe that only the chart title is visible; the chart itself is missing.

Expected Behavior:
The chart (including its title and visual content) should render completely every time the modal is opened.
