VaInput. isValid is not working with prop 'clearable'

[EugenGedroyc]

Vuestic-ui version: 1.10.3

• What is current behaviour
  isValid for useForm does not check that a VaInput is not fill if that VaInput has been cleared using the clearable button
  :rules="[ (value) => (value && value.length > 0) || 'Fill in the text box', ]"

• What is expected behaviour
  isValid should always return false if VaInput is empty. Now this behavior with VaInput cleared only manually.

• Any other useful information
  I think these are related issues:: VaInput: immediate-validation not work with clearable #3871
