Wasm-bindgen error messages are not displayed

Problem

dx bundle, dx build and dx serve suddenly all fail. However, running cargo build works fine.

dx bundle

The error message is not helpful. But I assume that wasm-bindgen fails, because it doesn't support the typetag crate.

Steps To Reproduce

This started after I added a dependencies to my Cargo.toml and used it in code:

typetag = "0.2.20"

Using typetag in wasm requires some extra setup, hence wasm-bindgen probably fails.

Expected behavior

Build works normally. Or at least I get a proper error message about why the wasm-bindgen file was not created.

Environment:

• Dioxus version: 0.6.3
• Rust version: 1.86.0
• OS info: Windows 11
• App platform: web

Questionnaire

I don't have time to fix this right now, but maybe later.

This is fixed now, thanks to #3797
