Warning in build = Use of eval in flexsearch

### Describe the bug

When I build my Histoire stories I get the following warning.
Use of eval in "node_modules/flexsearch/dist/flexsearch.bundle.js" is strongly discouraged as it poses security risks and may cause issues with minification.
Flexsearch is included in my bundle because Histoire requires it. I have no other packages that require flexsearch. Because of this warning I can no longer add the Histoire build to my Github actions.

### Reproduction

https://stackblitz.com/edit/histoire-vue3-starter-h4ejvh?file=package.json
If I use the Vue starter exactly as it is now and run `npm run story:build` I get this warning.

### Used Package Manager

npm

Start with the StackBlitz reproduction and its package.json, then run npm run story:build to confirm the flexsearch eval warning. Trace how Histoire brings flexsearch into the build and identify a project-level change that removes or prevents the warning. Done means the reproduced build completes without this warning.
