`@pdftron/webviewer` no longer works in `vite-rolldown` version 7.19.0

[chagweyh]

Starting from version 7.19.0, vite-rolldown changed the way default exports are resolved to make it more consistent with other bundlers, such as esbuild and webpack.

This change breaks @pdftron/webviewer. We now see the following error in the console:

Uncaught TypeError: WebViewer is not a function

Looking at https://cdn.jsdelivr.net/npm/@pdftron/webviewer@11.8.0/public/core/webviewer-core.min.js, both exports.default and __esModule are used, which may violate this rule: https://publint.dev/rules#cjs_with_esmodule_default_export.

WebViewer version:
11.8.0
