netteForms.js, line 515:
form.noValidate = 'novalidate';
Nette does not check whether given form is produced by Nette or other library and disables HTML5 validation for all forms. It is OK to do whatever Nette wants with forms created by Nette, but it must not touch other forms. When part of application uses another library, this behavior breaks things a lot.
Sollution: Do not set novalidate on entire form. Set it for individual inputs when nette attributes (e.g. data-nette-rules) are detected and processed. Or just don't use it when it is not required.
