Import simplebar with error undefined getOptions

After updating the simplebar library from 6.3.0 to 6.3.3, there is an error with the simplebar import. Now `import SimpleBar from 'simplebar';` displays the error:

`Uncaught TypeError: Cannot read properties of undefined (reading 'getOptions'): index.mjs`

Start by reproducing the failure from the reported `import SimpleBar from 'simplebar';` statement and inspect the generated `index.mjs` entry point named in the error. Compare the 6.3.0 and 6.3.3 import behavior; done means the import no longer throws the reported `getOptions` error.
