Specification

https://w3c.github.io/input-events/#dom-inputevent-datatransfer

Summary

Populate the dataTransfer property on input events with inputType of insertFromPaste, insertFromDrop, and insertReplacementText to provide access to clipboard and drag-drop data during editing operations in contenteditable elements. The dataTransfer object contains the same data that was available during the beforeinput event. This feature only applies to contenteditable elements. For form controls (textarea, input), the behavior remains unchanged - the data property contains the inserted text and dataTransfer remains null. Both Safari and Firefox already support this functionality. Chromium adopting this feature will enhance interoperability across browsers, providing a more consistent experience for web authors.
