This pull request improves the clipboard fallback handling by checking the return value of textArea.select(). This change provides clearer failure signaling when the copy operation cannot proceed and avoids unnecessary calls to document.execCommand('copy'). This approach aligns with previous decisions made to enhance performance and reliability in clipboard operations. Thank you for your contribution!

I appreciate you looking into improving the clipboard fallback in \utils/clipboard.ts. However, I have a concern with the changes: the .select()\ method on \HTMLTextAreaElement\ returns \�oid\ (undefined), not a boolean indicating success. Because of this, \const selected = textArea.select(); if (!selected) return false;\ will always evaluate to false and the function will never reach \execCommand('copy'). Please double-check the MDN documentation for \HTMLTextAreaElement.select()\ and revise this approach. I'll have to request changes for now.
