Can't always set React Native breakpoints in Chrome : <p>While debugging my React Native app in Chrome, I'm often unable to set breakpoints in the Sources tab.  When I click on a line of code to add the breakpoint, a breakpoint is added instead to the next function declaration line in my module.</p>

<p>This doesn't happen in all of my source modules, but often enough that it prevents me from debugging efficiently.</p>

<p>I'm currently using RN 0.22 but this has been happening on older versions of RN as well (e.g. RN 0.18).</p>
