Native browser form validation does not fire when submit buttons use #ajax
Needs work
we are currently making sure that submit buttons in Drupal ensure that the <form> is valid before it's going to be submitted. I figured out there is a problem with Autosave Form module since it's adding the hidden submit button that is automatically being clicked.
The result is a direct browser warning that the title field is not filled. We can easily fix this by just adding the formnovalidate attribute to the submit button, which is just for browser validation and does not interfere with Drupal's submit handling.
