8.7RC: Recaptcha v3 expect input submit

[bjarnef]

I noticed in the new Recaptcha v3 field type that the javascript expect an input using type=submit. This is fine, but it doesn't take into account that you might want to use a custom them overriding the Form partial view to use <button type="submit">Submitinstead. This is sometimes useful if you e.g. want to add an inlineicon or another child element, which<input type=submit /> doesn't allow.

We an of course override the Fieldtype.Recaptcha3.cshtml in our custom theme, but I wonder if we can modify the following the support <button> element as well?

hiddenField.form.querySelector('input[type=submit]').removeAttribute('disabled');

It could be something like:

hiddenField.form.querySelector('[type=submit]').removeAttribute('disabled');

or

var btnSubmit = hiddenField.form.querySelector('input[type=submit]') || hiddenField.form.querySelector('button[type=submit]');
btnSubmit.removeAttribute('disabled');
