[Image] Web Inspector vs Chrome DevTools

I've tried to debug React.js examples from <a href="https://facebook.github.io/react/downloads.html">https://facebook.github.io/react/downloads.html</a>. It was problematic for many of them:

I hosted the examples on GitHub pages: <a href="http://nv.github.io/webkit-inspector-bugs/react-0.14.0/examples/">http://nv.github.io/webkit-inspector-bugs/react-0.14.0/examples/</a>

<a href="http://nv.github.io/webkit-inspector-bugs/react-0.14.0/examples/basic-jsx-external/">http://nv.github.io/webkit-inspector-bugs/react-0.14.0/examples/basic-jsx-external/</a>
<a href="http://nv.github.io/webkit-inspector-bugs/react-0.14.0/examples/jquery-bootstrap/">http://nv.github.io/webkit-inspector-bugs/react-0.14.0/examples/jquery-bootstrap/</a>

WebKit Inspector:
  – Can’t set breakpoints in example.js.
  – When Inspector was opened after the page load, example.js isn’t showed in the resources. When Inspector was opened during the page load, example.js appears twice in the list.

Chrome DevTools:
  — Works fine.

WebKit Inspector:
  — Can’t set breakpoints on the text/babel inline scripts (which was converted to JS by Babel, e.g. &quot;browser.min.js&quot;).

Chrome DevTools:
  — The preprocessed inline scripts available as “embedded” virtual resources.</pre>
