    Don't bother checking input and textarea elements as complex contenteditable
    
    We want to check editable elements for descendants so we handle rich-text
    editors correctly. There's no point in doing this for native input and
    textarea elements. Granted, checking for descendants in childless elements
    should be super quick. But we're seeing some weird performance problems
    when doing this check for giant textareas in Chromium.
