bug 523 - disabling option elements fails in Safari on iOS

Issue: #523 Affects: Safari on iOS (iPod, iPhone, iPad) Select options support a disabled attribute so that developers can optionally disable individual options if/when they are not applicable. Safari on the desktop (Windows or Mac) both support this attribute however Safari on iOS (so iPod, iPhone, & iPad) the attribute doesn't actually do anything and the user is free to select the option even though it is supposed to be disabled. Example:
  <option value="1">first<option>
  <option value="2">second<option>
  <option value="3" disabled="disabled">third<option>
  <option value="4">forth<option>
If this select list were rendered on an iPhone or iPad you would be able to select the "thrid" option. It's not a Webkit bug, since the same select list will render perfectly on other tablets like the BlackBerry PlayBook.
Known Workarounds: Two. You'll need to either need to remove the options, or inform the user after their selection that it isn't valid (not recommended for usability purposes)
