missing retry strategy for fetching modules

[espretto]

Hello there,

the below linked error occurs primarily in mobile safari v17 which reportedly has network issues. Apart from that, mobile safari generally sets a lower timeout on script tags (~60 seconds) when compared to other browsers (5 minutes).

To solve the issue, a retry strategy comes to mind. I cannot speak to the side-effects of such a change but I do see merit in a runtime-option to set the timeout on the bundler level instead of relying on the browser settings.

If I am not mistaken, such functionality would be similar to webpack's chunkLoadTimeout.
