[Grida Canvas] virtual Copy-Paste not working on safari (fails with ckipboard write)

On Safari, the copy-paste won't work.
it only works with cut-paste.


Could be....
- the clipboard sync is not working due to more strict event chain on safari (since we are only partially relying on user event for writing to clipboard)
- the 'copy' is triggering to copy a div (surface, noop) content on safari

More details under investigation.
