Problem
CommentNodeRenderer.renderElement()pushes new disposables (DisposableStore, rendered markdown element, hover) intotemplateData.disposableson every call. When the tree recycles a template for a different element, these disposables accumulate because there is nodisposeElementmethod to clean them up between reuses. OnlydisposeTemplate(called on template destruction) disposes them.Fix
Add
disposeElement()that disposes and clears the per-element disposables array when a template is recycled, matching theIListRendererlifecycle contract.
