Use unsanitized HTML in demo clipboard read#3355
Merged

Conversation
Pass `unsanitized: ['text/html']` to `navigator.clipboard.read()` in the demo Paste button and PastePane so the read HTML is not sanitized by the browser. A local `ClipboardWithUnsanitized` interface is added since the option is not yet in the standard TypeScript Clipboard typings. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Pull request overview
Updates the demo clipboard-reading flows to request unsanitized text/html from navigator.clipboard.read() so the demo receives the original HTML payload (instead of browser-sanitized HTML), adding a local typing shim to satisfy current TypeScript DOM typings.
Changes:
- Pass
{ unsanitized: ['text/html'] }tonavigator.clipboard.read()in the demo Paste button and API Playground Paste pane. - Add a local
ClipboardWithUnsanitizedinterface to type the experimentalunsanitizedoption.
