Currently the use of raw identifiers in test names produces an invalid function name. Ident::new panics whenever it encounters the r# prefix, instead Ident::new_raw should be used.

However, the __wbgt prefix we append forms a valid identifier already. So removing the raw ident prefix ("r#") is the only thing required to create a valid function name.

Fixes #3288

already. So removing the "r#" prefix is the only thing required.

Fixes rustwasm#3288
