isPlainObject fails on IXSLTProcessor in IE

Description

I noticed this receiving an "object doesn't support this action" error when using $.ajax. It turns out, the underlying cause was an ActiveX objected nested deep within the context parameter. I'm not sure if any other ActiveX objects would cause this error... I found the problem with a progid of "Msxml2.XSLTemplate"

The problem can be isolated with the following:

var clsID = "Msxml2.XSLTemplate"; var oTest = new ActiveXObject(clsId); try{ $.isPlainObject(oTest); } catch(e) { /*object doesn't support this action*/ }

Actually, I did a search and the changes under Ticket #5669 fix the problem.

How does a non-Javascript object make it into isPlainObject()? Can you provide a complete example?

I think a host ActiveX object reports typeof(x)=="unknown" and it might be possible to check for that.

The changes referred to in Ticket #5669 (which addresses this issue) have since been marked as fixed and reference this ticket (#6488) as another source of where problems were also addressed. As this contained information which wouldn't classify it as a 100% duplicate I am marking this ticket as fixed.
