Eden Chuang 2e0a3f0ddb Bug 1546306 - Add an optional aFromChromeContext parameter to nsIScriptError::InitWithWindowID for the case the passed in windowId is zero. r=baku
In some cases, the nsIScriptError is initialized with zero innerWindowId, but is from chrome context.

For cases, this patch adds an optional aFromChromeContext parameter to nsIScriptError::InitWithWindowID, which default value is false.
