Pseudo State Drop Down Missing in Storybook 8

[flynnt]

This plugin provides a dropdown in the main toolbar that can be used to toggle various configured pseudo states on a component. As of Storybook 8, this dropdown no longer appears in the main toolbar (it was working in v7). I've seen #111, but the fix there does not seem to have brought the dropdown back for me. I did a reduced test case for this with a very minimal component and Storybook implementation, but I am still not seeing the dropdown. I can verify that the add on is still working behind the scenes, because setting something like:

  parameters: {
    pseudo: { hover: true },
  }

still has the effect of generating the .pseudo-hover-all selector in the rendered CSS.

The setup I am using to test this is:

React + Typescript + Vite (in library mode) + SWC
Storybook v8.0.8
Storybook Addon Pseudo States v3.0.1

Let me know if I can provide more information or I can help to troubleshoot this further. Thanks!
