title: SyntaxError: 'with' statements are not valid in strict mode
body: <p>I'm getting this error in safari console when I try to do anything from a breakpoint. Bug report here: <a href="https://bugs.webkit.org/show_bug.cgi?id=83267">https://bugs.webkit.org/show_bug.cgi?id=83267</a></p>
  
  <p>Does anyone have a workaround? For reasons that I am assuming are related to this javascript has ceased to run on my site in safari. </p>
  
  <p>edit: the bug report also contains repro steps. </p>
  
  <p>another edit: I'm not using a "with" statement. This is a bug from the safari console. </p>
