[Resource Consumption] minimized iframes consume resources and are unbounded

Minimized iframe surfaces retain their live documents without a count limit so minimizing another browser never discards unsaved page state or turns reattachment into a reload.

Hidden iframes can still consume memory and run JavaScript, timers, sockets, and media. Retaining arbitrarily many minimized iframes therefore allows resource consumption to grow without a Dormouse-imposed bound.

Priority: low. This is an accepted tradeoff for preserving content state. A future improvement could warn users when retained iframe resource use is high. Do not silently evict or reload minimized documents to enforce a cap.

The current eight-surface parking cap is being removed as part of the minimize/reattach lifecycle fix. This issue tracks the resource-consumption follow-up, not reintroducing that cap.

Commencez par retracer le cycle de vie de l’iframe minimisé et la manière dont les documents conservés consomment des ressources. L’Issue ne nomme ni fichiers, ni tests, ni seuils, ni implémentation concrète ; clarifiez le comportement de l’avertissement et ses critères d’achèvement avant de commencer le travail.
