Temporal workaround for WhatsApp Web paste Ctrl+V behaviour.
Note: This script is no longer needed, as WhatsApp has resolved the bug that previously prevented pasting on the web version. Once you receive the latest update for WhatsApp Web, you'll be able to paste content as usual. Additionally, you can revert dom.events.asyncClipboard.readText to its default state of false. Thank you for your support.
Requires dom.events.asyncClipboard.readText to be enabled in about:config.
