    all: add support for synchronous callbacks to js/wasm · 6dd70fc5
    Richard Musiol authored
    With this change, callbacks returned by syscall/js.NewCallback
    get executed synchronously. This is necessary for the APIs of
    many JavaScript libraries.
    
    A callback triggered during a call from Go to JavaScript gets executed
    on the same goroutine. A callback triggered by JavaScript's event loop
    gets executed on an extra goroutine.
    
    Fixes #26045
    Fixes #27441
