The filter drove every row's IsExpanded from the single IsFiltering flag via a TreeViewItem style setter. Expansion lived nowhere else: user gestures (expander arrow, double-tap, arrow keys) all write the property with SetCurrentValue, which the style binding overwrites on every flip of the flag. Starting a filter therefore destroyed the expansion state the user had built up, and clearing it collapsed the whole tree, burying the still-selected row under collapsed groups. Row state (visibility + expansion) now lives on a StepNodeViewModel wrapper per step, two-way bound from the style, so gestures persist in the view-model. A filter session snapshots expansion on entry, hides non-matches and opens only the paths to matches while typing, and on exit restores the snapshot and re-expands the selected step's ancestors so the selection stays visible. Wrapping is skipped for reference-equal step lists because step replays re-report the same run and a rebuild would wipe the state mid-navigation.
