VBox doesn't detect "modern standby" sleep mode on Win11 host

Description
It looks like many newer laptops that come win win11 have "modern standby" as the only available sleep option. When such laptop is put to sleep VBox doesn't detect it, leading to a broken VM on wake up (in my case my VM session was killed by a watchdog when laptop briefly woke up to switch from sleep to hibernate).
It looks like VBox needs to call RegisterSuspendResumeNotification in its HostPowerWin implementation to get notification for modern standby, see chromium code: https://chromium.googlesource.com/chromium/src/base/+/master/power_monitor/power_monitor_device_source_win.cc#119
