Prune decoded image resources retained by active documents once they grow beyond a recent working set. Route-heavy applications can load many unique images through one Document, and the shared resource and available-image caches would otherwise keep decoded image data alive after the DOM stopped using those images. Track cache touches and evict least recently used decoded images from both caches. This keeps active documents from accumulating unbounded decoded image resources while preserving a small hot cache for repeat loads.
