Submit button not disabled with input type number, value=0 and min="10"

[goog62]

I expected the validator to catch that 0 is less than the minimum value of 10 and disable the submit button when the form first displays:

`

Amount

Submit `

Here's the Fiddle https://jsfiddle.net/goog62/cgeLj1ty/

I'm getting around the problem now on the server side by replacing "0" with "". Any suggestions?

Weird... Calling HTMLElement.prototype.checkValidity() on the field returns false, but the validator isn't seeing the error for some reason. Seems like a strange bug.
