[ExtJS 6.2.1] Fieldset with checkboxToggle set form state to dirty

[ffayolle]

In this example, if you expand a fieldset with a checkbox, the form's state becomes dirty (the console.log's prove that):

As this isn't a form field but rather a presentation item of the fieldset, that's not what I would expect.

The workaround I found is to set isFormField to false in the checkbox attribute

It's arguable whether or not the fieldset checkbox is a presentation item only, it largely depends on the form itself, so I'm not really sure this is a bug.

How should we tell the form it should not consider the checkbox for its dirty state then?

I think as you have it is fine.

Well, that's a hack. `isFormField` is a readonly property normally.
