title: How durable are IElementHandle objects?
body: <p>Rather impressive so far, just starting with Playwright, really nice, really impressed so far!</p>
  <p>I'm curious about the durability/life cycle for elements we get back from QuerySelector*() methods.  Given most web libraries/frameworks like Angular and React may remove and graft in a new UI element...   Should we code in such a way to assume the elements are more transient and should always perform a QuerySelectorAsync() prior to using, given my element was previously fetched?  So far it seems values is fetched real time, i.e get the control, check value, change value, getting the value now will get the current/updated value.</p>
  <p>More interested what is expected behavior after the may DOM updated by our respective UI Libs/Frameworks?</p>
  <p>Thanks in advance :)</p>
