Responding to review comments on Async Clipboard APIs bug

See specific comment here.

From https://developer.mozilla.org/en-US/docs/Web/API/DataTransfer/getData, we see that

The DataTransfer.getData() method retrieves drag data (as a DOMString) for the specified type. If the drag operation does not include data, this method returns an empty string.

This does not mention anything about actually retrieving data from the clipboard. But this could be a typo. Still, I’m having a hard time locating where in DataTransfer::GetData DataTransferItem::DataNoSecurityCheck(...) gets called. I’m going to debug and see at which point the above function gets called.

Update

I stepped through Clipboard::WriteText(...) and discovered that eventually DataTransferItem::GetData(...) indirectly calls DataTransferItem::DataNoSecurityCheck(...), so I had to refactor my code.
