Fix copy page button not working in Safari#5560
Merged
Conversation
Safari requires clipboard writes to begin in the synchronous call stack of a user gesture. The previous code awaited fetch() before calling navigator.clipboard.writeText(), breaking the gesture chain. Use ClipboardItem with a Promise<Blob> so the clipboard write starts synchronously while content resolves asynchronously. https://claude.ai/code/session_018e1sgeEGsu8UsSYkq6tkfb
Remove the ClipboardItem.supports check and writeText fallback. All modern browsers support ClipboardItem with Promise<Blob>, and the supports() method may not exist in older Safari versions that still need the synchronous gesture fix. https://claude.ai/code/session_018e1sgeEGsu8UsSYkq6tkfb
