Summary

When hovering over an image clipboard item in the menu, a scaled preview popup is displayed next to the cursor, making it easy to identify images without pasting them.

  • Preview is scaled down to max 500px, positioned near the mouse cursor
  • Clamped vertically to stay within screen bounds
  • Framed with a visible gray border to distinguish from the background
  • Preview is lazily loaded and cached per menu item
  • Works for both ImageClipboardItem and FileClipboardItem (image files)
