Research direction
Start by reproducing the JavaScript snippet with element.attr(), element.removeAttr(), and element.findView(paper), comparing the root element's test attribute with the null workaround. Trace the root attribute handling from these entry points. Done means removeAttr('root/test') makes hasAttribute('test') false, matching the workaround.
