Replace all pointerdown events with mousedown events

[samelie]

• Changed all 'pointerdown' event listeners to 'mousedown'
• Updated corresponding event handler method names (onPointerDown -> onMouseDown)
• Updated private property names (_onPointDown -> _onMouseDown) for consistency
• Fixed TypeScript event parameter types (PointerEvent -> MouseEvent)
• Updated related pointer events (pointermove, pointerup, pointercancel) to mouse events (mousemove, mouseup, mouseleave) in splitview
• Maintained full functionality while switching from pointer events to mouse events

Can you explain why you wanted to use mouse events rather than pointer events?

[samelie]

Hi matteo this is a fantastic library. Thank you. If my tool works out then I can definitely sponsor you.

I'm developing a tool Inside of adobe CEP ( custom panel inside of Adobe products are a modified chromium )

I discovered after many painful experiments that adobe CEP blocks pointer events but allows mouse events ...

CEP also does some things to the events where event.defaultPrevented is true therefore blocking a lot of the tab selection

I'm not sure what to do with all this code that Claude wrote
