A recently deployed TBPL parser improvement has found a whole bunch of log spam in green debug mochitest-browser-chrome runs. a) Should these be making the test run fail? b) We should handle/fix, so we don't spam the annotated failure summary. eg: https://tbpl.mozilla.org/php/getParsedLog.php?id=25965644&tree=Mozilla-Inbound#error2 { 04:31:35 INFO - TEST-INFO | chrome://mochitests/content/browser/browser/devtools/styleeditor/test/browser_styleeditor_bug_740541_iframes.js | Console message: [JavaScript Warning: "Error in parsing value for '-moz-box-ordinal-group'.

This shouldn't be too hard to fix, I imagine.

Fix for the "TypeError: this.selectedEditor.sourceEditor is null". I can't figure out where that -moz-box-ordinal-group is coming from.

(In reply to Heather Arthur [:harth] from comment #3) Thanks!

Assuming no QA needed here. Please remove [qa-] from the whiteboard and add the verifyme keyword if this needs QA.
