HTML5 Form verification blocks the password to 16 chars, how to change?

HTML5 Form verification blocks the password to 16 chars, how to change?

I did a simple login form, but a customer wants to input a password with
24 characters. Strangely enough, it seems that the form validator from
HTML5 is blocking it at 16 which is really annoying. I tried pattern but
didn't work. Any ideas?
<input type="password" id="password" name="password" pattern=".{5,25}"
required />
So I want to limit it to 24 characters instead of default 16.

Thanks in advance for your help.
