Wiki / WYSIWYG cancel button submits the edit form

Right now the cancel button is implemented in editactions.vm like this:

<span class="buttonwrapper">
  <input class="button" type="submit" name="formactioncancel" #if ($keyboardShortcutsEnabled)title="$msg.get("core.shortcuts.edit.cancel")"#end value="$msg.get("cancel")" onclick="cancelEdit();"/>
</span>

Notice the

type="submit"

. I think the cancel button shouldn't submit the edit form. The new WYSIWYG has an issue because of this. If the user manages to get into an invalid state in which the save throws and exception, he cannot cancel the editing because the edit form would still be submitted and the WYSIWYG Conversion Filter would still throw an exception.

I tried using an anchor but the cancel button doesn't look the same.
