Start at packages/f2/src/components/tooltip/tooltipView.tsx around line 272, linked in the issue. Compare the itemMarkerStyle default with the value supplied through props and reproduce the reported override using the referenced source. Done means the props-provided style is no longer unexpectedly overridden by the default.
