[1] says:
Note: DOCTYPEs are required for legacy reasons. When omitted, browsers tend to use a different rendering mode that is incompatible with some specifications. Including the DOCTYPE in a document ensures that the browser makes a best-effort attempt at following the relevant specifications.

The interactive form validation is incompatible with prior HTMLs.  So browsers may disable it for non-HTML5 modes to follow prior HTML specifications.

> That's not how standards work. When you find something in the spec you don't like, you bring it up with the working group, you don't just unilaterally get to ignore the spec. Otherwise, you're no better than Microsoft. Send an e-mail to whatwg at whatwg.org saying what the problems were, and we'll fix the spec. It won't be by adding yet more quirks differences.

I posted a part of issues to whatwg.  See the thread with subject "Form validation against invisible controls", and my conclusion is to disable the interactive validation in non-HTML5 modes. I'll post this conclusion soon.

> Note that Chrome is very buggy if it is just blocking form submission without telling the user why.

yeah, I understand it.
