Design Mode Text Editor code issues should only be shown in the text editor view

While typing in qml code in text editor the issues are shown also in the Form Editor.
It would be better to show the issues and offending lines only in the text editor rather than in the form editor.
Also the updates to the form editor should be done after a second or two typing has ended. Currently it's trying to keep up realtime what has been typed in to text editor. So when the code that's being typed in hasn't been completed yet, it's showing an error in the form editor.
