"Should never destroy FnMut" error when running readme example

When trying to run the readme example, I get the following error in Firefox and Chromium:

Using console_error_panic_hook::set_once();

wasm-pack 0.6.0
cargo 1.34.0-nightly (5c6aa46e6 2019-02-22)

I tried to follow the readme instructions 1:1, but it's possible that I'm missing something :)
