With Locate Selected Objects on, an object selected on the canvas had the
layers and groups around it opened even when Show Layers Only, a search or
the filter left it without a row. The panel did not scroll to it, but the
rows stayed open, so they showed once the panel listed every row again.
The panel now opens the rows around the object only when the object has a
row once they are open. Otherwise it opens nothing and scrolls as with the
option off. The Layers panel entries in docs/mcp.md and
docs/target-app-parity.md describe this.
