Doc indexing silently failing for Storybook

At my company we have a corporate design system and React ui-kit that implements it and is served from a public URL that you can reach here: https://ui-retail.dds-omega.ru.
Cursor fails to index these Storybook components. It shows in the ui that indexing of the provided url is succesful and finished but when I open the tooltip that lists all of the pages indexed it never stops showing me the “Indexing…” message which I take is basically saying that it failed and did so silently. Another reason to belive that it failed is because the AI chat does kinda ■■■■ at doing anything related to this ui-kit library meaning that the indexing did not happen at all or was very poorly performed. The issue with indexing may lie in the fact that storybook paths are structered in an odd way, for example, an Avatar component story can be accessed with this url: https://ui-retail.dds-omega.ru/?path=/docs/components-avatar--документация. It is kinda weird as the path is contained as url parameter. It also includes cyrilics, something to keep in mind I guess. All in all, there are a few reasons it could fail here as you can see.
