When the X11 connection is dead, WmHints::set returns a ConnectionError. The previous code called expect_then_ignore_error which panics on the send error. This caused Warp to abort (Sentry WARP-CLIENT-BETA-STABLE-89S1) when ringing the terminal bell while the window was inactive on a dead connection. Replace the panic with an if-let that silently drops the send error, matching how the get side of the same function already handles failures. On success, the cookie error is still ignored the same way. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
