These attributes are working on other FORM elements except for LABEL which has
already been written up in bug
http://bugzilla.mozilla.org/show_bug.cgi?id=83733. There is another general bug
for 'onkeypress'- http://bugzilla.mozilla.org/show_bug.cgi?id=87555.

Let's shake a bit this tree.

HTML5 says that it must be supported
https://html.spec.whatwg.org/multipage/webappapis.html#handler-onkeypress
https://www.w3.org/TR/html5/webappapis.html#handler-onkeypress

This is creating a Webcompat issue

The markup is 

```html
<input name="AcademicTime" value="0" 
       class="txt_Num" 
       onkeypress="if(isNaN(String.fromCharCode(event.keyCode))) return false" 
       type="text">
```

Perhaps if we find more sites breaking due to this we can bump the priority.

Migrating Webcompat whiteboard priorities to project flags. See bug 1547409.
