(This is for compiling WASM). I've tried both versions where people reported it didn't happen, as well as the version after it was supposedly fixed. Referring to: rustwasm/wasm-bindgen#2776

# If you want to use the bleeding edge version of egui and eframe:
# egui = { git = "https://github.com/emilk/egui", branch = "master" }
# eframe = { git = "https://github.com/emilk/egui", branch = "master" }

# If you fork https://github.com/emilk/egui you can test with:
# egui = { path = "../egui/crates/egui" }
# eframe = { path = "../egui/crates/eframe" }

Used to compile

Can you check out latest egui master and run:

scripts/setup_web.sh
scripts/build_demo_web.sh

I think it should work. Please re-open the issue if it dosn't!
