It looks like Druid tries to call Application::global() when doing stuff with the clipboard but this panics, maybe because the global app is stored in a thread_local! variable which doesn't work in wasm.
Steps to reproduce
Clone the repo and then run:
❯ wasm-pack build --target web --dev
❯ http
Open browser and navigate to http://localhost:8000/
Try to cut/copy/paste any text in the textbox
See the following error in the JS console:
hello_web.js:333 panicked at 'There is no globally active Application', /.../druid/druid-shell/src/application.rs:109:35
