Suggested change
* `web-sys` crate now fully works on `no_std`.
* Fixed `no_std` support for all APIs in `web-sys`.

It sounds like the std Vec usage was on purpose, it was just an oversight 😅!

Just for context: this is always a bug, because crate features have to be additive and they are not supposed to break compilation when you add a crate feature!

This bit me while working on no_std for Bevy (you can read about the efforts here). For future reference, if you do this:

#![no_std]

#[cfg(feature = "std")]
extern crate std;

You can have an std feature without toggling the implicit prelude, which catches these kinds of import issues when compiling with all features.
