Errors in console
I'm seeing the following errors in the console quite regularly (repeating)
chartResponse.js:91 Uncaught TypeError: Cannot read property 'querySelector' of null
at ChartResponse.makePingSpan (chartResponse.js:91)
at ChartResponse.updatePingText (chartResponse.js:105)
at n.<anonymous> (chartResponse.js:27)
at n.emit (index.js:83)
at n.onevent (index.js:83)
at n.onpacket (index.js:83)
at n.<anonymous> (index.js:83)
at n.emit (index.js:83)
at n.ondecoded (index.js:83)
at a.<anonymous> (index.js:83)
I believe this is code which belongs to this add on.
