Hi There,
Thanks for writing in and sorry you’re having this issue, this is a bug that is already on our reported list. Temporary fix is adding this under Custom > CSS in the Customizer.
a:focus, select:focus, input[type="file"]:focus, input[type="radio"]:focus, input[type="submit"]:focus, input[type="checkbox"]:focus {
outline: none !important;
}
Hope it helps, Cheers!
Joao
