Dragging a Window Affects Other Windows When Multiple Are Open

Issue:
When two or more layers of windows (e.g. modals, overlays, or panels) are open in the editor, dragging one window can unintentionally cause other windows to move as well. This leads to unexpected behavior and UI glitches.

✅ Steps to Reproduce

1. Open multiple draggable windows in the editor (e.g., Inspector + Insert Panel or a modal + nested dialog)

2. Try to drag the topmost window

3. Observe that other windows may also move or jump with it

🤔 Expected Behavior

Dragging should only affect the specific window being interacted with. Other windows should remain in place unless explicitly selected and dragged.

🚨 Actual Behavior

Dragging one window sometimes results in:

• Multiple windows moving together

• Positioning conflicts between overlapping windows

• Incorrect z-index handling

⚠️ Impact

Medium – causes usability frustration and layout instability when managing multiple tool panels or modals.

✅ Suggested Fix

• Ensure each window has isolated drag behavior

• Prevent drag propagation between stacked or nested windows

• Verify z-index and pointer event handling to isolate interactions
