Handle Duplicate clauseId from Copy/Paste

[irmerk]

Further issues should consider:

• Handling different transfer.type situations

  • Editor instance (Slate) to another editor instance (Slate)
  • Raw HTML (Chrome to VSCode to Chrome)
  • Editor instance (Slate) to Google Docs and back (recognize <clause> formatting)

• Ensure onPaste handlers are not doubling up work for any transfer.type cases

  • @accordproject/cicero-ui/src/plugins/ClausePlugin
  • @accordproject/markdown-editor/src/SlateAsInputEditor

• What fragment.type results when copying pasting from one editor to another instance of an editor?

  • fragment as a transfer.type is a Slate DOM block fragment, not HTML anymore, so copying and pasting from the same editor into itself should be a fragment
  • However, copying pasting from one editor to another instance of an editor may result in HTML or fragment, needs experimentation

• Preserve formatting, if H1 in HTML, we should be preserving the formatting

  • Slate has a mechanism for mapping from HTML tags to Slate blocks here
