Notes:

• Reproduction is inconsistent
• CQA was unable to reproduce the issue on our local devices, because we don't have the exact device model reported by the user
• The “Windowed apps” option is available starting from iPadOS 26
• When the bug reproduces on simulator, the error “<0x10290ab80> Gesture: System gesture gate timed out” in Xcode is logged
• On 6000.5.0a5 version, the dropdown flickers when selecting an option
