Issue description

Hello!

I stumbled accross some sort of bug.

When using the NotifyIcon class and setting an icon, the notifications sent by that NotifyIcon using ShowBalloonTip don't match if that icon was updated. This only happens on Windows 11. I tested it on various machines, 3 Windows 10 machines and 3 windows 11 machines, one of them Windows 11 machines was 24H2. all windows 10 were 22H2.

Steps to reproduce

I created a repo for that! https://github.com/elixss/NotifyIconTest

Clone it, run it and compare: on windows 10 the icons will match from notifications and tray, on windows 11 they won't.
