Tools like Easy Move+Resize use the macOS Accessibility API to find and
move/resize windows. They call AXUIElementCopyElementAtPosition to get the

The isAccessibilitySelectorAllowed: whitelist was blocking these selectors,
preventing external window management tools (Easy Move+Resize) from working with
kitty.
