Splitter: Resize not stopped at limits when using more than 2 vertical panels

Describe the bug

When using more than 2 vertical panels, dragging the resize handle beyond the top or bottom limit results in all panels being slightly resized. Later, on the next resize operation, panel sizes might appear to "jump" when starting the drag.

Steps to reproduce the behavior

1. Open the linked Stackblitz project.
2. Drag any of the resize handles beyond the top or bottom limit.

Expected behavior

No response

Start with the linked StackBlitz reproducer, especially src/App.jsx, and reproduce the issue with more than two vertical panels. Trace the resize behavior from the panel and handle setup; done means dragging beyond either limit leaves panel sizes stable and a later resize does not visibly jump.
