The cluster and node pages swap their live part every few seconds, and the forms inside it went with it: what was typed, an open choice, the focus. Filling one in raced the clock. The swap now waits while a field in the live part has the focus or a form in it has been typed into and not sent; sending it, or leaving the page, ends that. The mirror page's reload during a download goes through the same check instead of http-equiv. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
