Having multiple validationErrorClasses displays the error twice when submitting the form again

[thomasaull]

I'm using the following options:

ValidForm(form, {
  validationErrorClass: 'Input-error has-text-danger'
})

while it does work perfectly when the error is shown for the first time, every subsequent display does not remove the first one – or every time I click on submit another error message is added:

Having only one validationErrorClass works perfectly:

ValidForm(form, {
  validationErrorClass: 'Input-error'
})

Ping me if you need a test repo :)
