GNOME does exactly the same thing.
very noticeable and annoying when transferring to slower media like usb sticks, sometimes it takes tens of minutes to unmount after copying a large file because its actually still writing.
i bet MANY people are left with halfway stuff written on their usbs after being in a rush and removing it insecurely on linux after the transfer is “done”. this should absolutely NOT be a thing.
considering most aaas are junk these days, this is a great out.
