Description:
jellyfin-web currently comes with a `prepare` script, which builds the production webpack when `npm ci` is ran: https://github.com/jellyfin/jellyfin-web/blob/55714d5341d6bbfdb4d8b0b4c9b6955d4db14f34/scripts/prepare.js
Thus, the webpack is currently built twice, once in the prepare() step by `npm ci` and again in the build() step by `npm run build:production`.

The script has been removed 6 months ago on the master branch, but is still present on the release-10.8.z branch this package is built from.
I assume the script will be gone with the 10.9.z release series.
Until then, the environment variable `SKIP_PREPARE=1` can be set to skip building the webpack during `npm ci`.

Additional info:
* package version(s) 10.8.10-3
