title: Modifying keyboard toolbar / accessory view with WKWebView
body: <p>I'm using a WKWebView with a content-editable div as the core of a rich-text editor, and would like to modify the top toolbar above the keyboard—the one that contains the autocorrect suggestions and formatting buttons. (Not sure if this counts as an input accessory view or not).</p>
  
  <p>I've found a few posts showing how to remove the bar, but none of them seems to work, and ideally I'd like to keep the autocorrect part anyway.</p>
  
  <p>At least one app, Ulysses, does this (though I don't know if it's with a web view):</p>

  <p>And indeed, I'm pretty sure I can achieve it by doing surgery on the keyboard view hierarchy...but that seems like a tedious and brittle approach.</p>
  
  <p>Is there a better way?</p>
  
  <p>Thanks!</p>
