Describe the bug

After upgrading Nuxt from v3.10.3 to v3.11.1 I get this error when I try to show the application from a Safari browser with a version <= 16.3.

For reproduce the issue I started from the Nuxt 3 base template (who is working) and I added a simple page.

It seems like some regular expression aren't supported in this browser version (as you can read HERE)

Safari v15.5:

Safari v17.3:

I think the following information could be usefull.

Quick edit: Just tested on a older version of Safari. And the problem is this:
new RegExp("(?<!\/)\/(?!\/)");

@Rizzato95 @hankdetank try updating ufo to the latest (1.5.2) by refreshing the lockfile as there has been a hotfix. But as nuxt is using the function for public paths (

nuxt/packages/nuxt/src/core/templates.ts

Line 330 in 6f2e7a8

'import { joinRelativeURL as joinURL } from \'ufo\'',

) it might not fix it.

[pi0]

Browser compatibility with ufo.joinRelativeURL is increased in ufo@1.5.3 (via unjs/ufo#228).

Please make sure to update the lock file manually (or using npx nuxi upgrade --force), remove node_modules if the issue exists, and check pnpm why ufo or npm why ufo to see why an older version of ufo might have been stalled.

This seems to be back with ufo 1.5.4 :/

Please raise it upstream with ufo 🙏

@ChristopheCVB I thought I was having an issue as well, but I was using a negative lookbehind in my code. Just FYI in case that helps!
