.tippybox has 'color: white' set on it, unsure why

[sebpowell]

I'm using Tippy.js with the TipTap editor – I recently noticed that the .tippy-box class has color: white set on it, like so:

This is how Tippy is being instantiated:

export const suggestions = {
  pluginKey: new PluginKey("SlashCommandSuggestions"),

  render: () => {
    let component: ReactRenderer;
    let popup: { destroy: () => void }[];
    let localProps: Record<string, any> | undefined;

    return {
      onStart: (props: Record<string, any> | undefined) => {
        localProps = { ...props, event: "" };

        component = new ReactRenderer(CommandList, {
          props: localProps,
          editor: localProps?.editor,
        });

        popup = tippy("body", {
          getReferenceClientRect: localProps.clientRect,
          appendTo: () => document.getElementById("tip") || document.body,
          content: component.element,
          showOnCreate: true,
          interactive: true,
          trigger: "manual",
          placement: "bottom-start",
        });
      },

      onUpdate(props: Record<string, any> | undefined) {
        localProps = { ...props, event: "" };

        component.updateProps(localProps);

        (popup[0] as any).setProps({
          getReferenceClientRect: localProps.clientRect,
        });
      },

      onKeyDown(props: { event: KeyboardEvent }) {
        component.updateProps({ ...localProps, event: props.event });

        (component.ref as any).onKeyDown({ event: props.event });

        if (props.event.key === "Escape") {
          (popup[0] as any).hide();

          return true;
        }

        if (props.event.key === "Enter") {
          return true;
        }

        return false;
      },

      onExit() {
        if (popup && popup[0]) popup[0]?.destroy();
        if (component) component.destroy();
      },
    };
  },
};

I'm not sure what is adding this color attribute – is it something that is set within Tippy, or could it be coming from elsewhere? I initially thought it might have something to do with the theme prop (https://atomiks.github.io/tippyjs/v5/themes/), but I'm not actually using a theme so shouldn't it just use the default body color?
