The WASM interface has not been initialized

[AlexD10S]

A hacker of the Blockspace Synergy Hackathon reported this issue when trying to deploy a ink!v6 smart contract using https://ui.use.ink/

index-Bcx2wWl-.js:56 Error: The WASM interface has not been initialized. Ensure that you wait for the initialization Promise with waitReady() from [@polkadot](https://t.me/polkadot)/wasm-crypto (or cryptoWaitReady() from [@polkadot](https://t.me/polkadot)/util-crypto) before attempting to use WASM-only interfaces.

The deployment works fine using https://inkv6alpha.netlify.app/ and cargo-contract

I have been able to replicate the issue with Brave browser

Seems to be fixed when v6 is the default #577
To be confirmed once merged
