User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20100922 Firefox/4.0b7pre Build Identifier: The maxlength attribute applies to <input type="file"> fields, causing them to block the form they are associated with from being submitted. From the reading the spec, I gather this isn't supposed to happen (it's supposed to be ignored), the documentation on the MDC also says this. https://developer.mozilla.org/en/HTML/Element/input#attr-maxlength Reproducible: Always Steps to Reproduce: 1. Open data:text/html,<input type="file" maxlength="1"> 2. Select a random file 3. Notice it gets the red box-shadow specifying it's "invalid" Actual Results: maxlength attribute is ignored, control isn't marked invalid.
This needs to block, I think. Mounir, please fix?

Ok, the problem is maxlength should only apply to some types and we are checking maxlength whatever the type is, which is wrong.
