Original Pull Request: https://github.com/microsoft/terminal/pull/6631

State: closed
Merged: Yes

Before sending calling the HandleClipboardData member function on
the PasteFromClipboardEventArgs object when we receive a request
from the TermControl to send it the clipboard's text content, we
now display a warning to let the user choose whether to continue or
not if the text is larger than 5 KiB or contains the new line
character, which can be a security issue if the user is pasting the
text in a shell.

These warnings can be disabled with the largePasteWarning and
multiLinePasteWarning global settings respectively.

Closes #2349
