            receive remote changes and so it can wipe the newly inserted content (because
            chainpad work synchronously), and the merged text is missing a few characters.
            To fix this, we have to call `framework.localChange` sooner. We can't listen for
            the "keypress" event because it is trigger before the character is inserted.
            The solution is the "input" event, triggered by the browser as soon as the

/*  CKEditor4 is, by default, incompatible with strong CSP settings due to the
    way it loads a variety of resources and event handlers by injecting HTML
    via the innerHTML API.

    In most cases those handlers just call a function with an id, so there's no
    strong case for why it should be done this way except that lots of code depends
    on this behaviour. These handlers all stop working when we enable our default CSP,
    but fortunately the code is simple enough that we can use regex to grab the id
    from the inline code and call the relevant function directly, preserving the
    intended behaviour while preventing malicious code injection.

    Unfortunately, as long as the original code is still present the console
    fills up with CSP warnings saying that inline scripts were blocked.
    The code below overrides CKEditor's default `setHtml` method to include
    a string.replace call which will rewrite various inline event handlers from
    onevent to oonevent.. rendering them invalid as scripts and preventing
    some needless noise from showing up in the console.

    YAY!
