WebContainer unavailable in latest Safari

[bcw222]

Describe the bug

I cannot use pnpm install to install dependencies in Safari 18.2.

Link to the blitz that caused the error

https://stackblitz.com/github/EveSunMaple/Frosti

Steps to reproduce

Simply open this link in Safari and wait for its auto configuration to fail on installing dependencies.

Expected behavior

Successfully install dependencies and work normally.

Parity with Local

• I have run the project in my local machine and I could not reproduce the issue.

Screenshots

Platform

I have this same error, but I think it's always happening, unrelated to pnpm:
