Ext.data.request.Ajax doesn't fire requestexception on failed requests (6.6.0)

[sarimarton]

When there's no service, and I send an http request, Chrome DevTools' Network panel shows a red entry with a status "(failed)". These requests normally triggered a requestexception prior to Ext JS 6.6.0 Classic.

In Ext JS 6.6.0, the method Ext.data.request.Ajax-static-method-parseStatus has been modified which results in these requests being recognized falsely as successful.

https://docs.sencha.com/extjs/6.6.0/...od-parseStatus

The problem is that success:true is allowed when status is 0 and response length (len) is a number, but the new modifications set the len variable manually to 0 if responseType is 'json', which in turn probably depends on how the request is configured...

So failed requests falsely result in successful response.
