form OnSubmit trigger on click of any pell formatting button inside form.

Hi @jaredreich,

I kept the pell editor inside a form which have an onSubmit event handler on it. While I click on any of the formatting button the form onSubmit got called.
The only workaround I got it to check the event inside the onSubmit method.

I wonder if this can be correctly handled in the pell.

I will raise a PR with the solution which I think of.

Reproduce the issue by placing the pell editor inside a form and clicking each formatting button, then inspect how those buttons are created and handled. Done means formatting clicks no longer trigger the surrounding form's onSubmit handler while the editor actions still work.
