Add ability to dismiss summary

Issue

• Once a summary has been generated, there is no way of removing the element from the page if needed.
• With the latest updates, we have also lost the ability to copy-to-clipboard.

Proposal

• Add a dropdown disclosure menu that will have the ability to:
  • Copy to clipboard
  • Remove summary

Proposal

Things to validate

• Are users dismissing the summary?
• Is the Copy to clipboard option getting used?
