    • Originally reported at https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/10538279/, it appears this is either a regression or it was never actually fixed.

      `` will let you enter abc. You will get a validation error on form submit, but the expected behavior is that the input box will not let you input the letters in the first place.

      This is important because if you are using the value elsewhere in the page, you can’t use HTML5 validation to ensure that the input box only contains expected values, you must resort to JavaScript validation.

    • This issue appears to be related to small step sizes and numbers near the min. Using step="0.01" min="1.0" and 1.2 will validate but anything between 1 and 1.19 will not validate. If I change min="2" it will not validate with 2.01.

      Note: Problem goes away if min="0".
