html.elements.input.input-email - No native error message when writing non-email text

What information was incorrect, unhelpful, or incomplete?

When using Firefox browser on an android mobile device, we noticed that when a user writes text that isn't an email in an email input field on a website, there is no native error message on submit, unless the text explicitly has an @ sign. For example, writing test won't give an error, but writing test@test will give an error. We've tested this on iOS browsers and Android browsers, and seems only Firefox's Android browser seems to have this issue. It works perfectly as expected on Firefox iOS.
