Yep. Almost all operating systems have a bufor that tell programs file was moved when it is still in the process. It makes perfect sense, it speed things up and extends the lifespan of the device.
You can flush that bufor manually with just the sync command or disable it for whole partition with -o sync option. Technically you should unmount drives before unplugging for safety anyway, but people are stupid or more important lazy and in my opinion for external devices mounting with sync really should be the default. Maybe some low-level developer would disagree.
To be fair in the other direction. Debian and Ubuntu and forks have it. They handle pretty much all filesystems fine, which is indeed impressive. Suprisingly Windows also has pretty good EXT drivers, so in a way the world is in harmony :D .
This is funny, because copying files to a USB flashdrive, is just inherently disfunctional in linux.
TRUE!!! Why “user friendly” distros does not mount removable drives with sync option by default is beyond me.
Hang on there is a sync option? Does that make the progressbar work? If so why is it not enabled?

Progress bars are handled by the applications themselves, whether flushing happens or not;
immediate flushing does not increase storage lifespan, in fact letting the OS decide when to do it may allow wear-leveling to work better.
(Though, IMO immediate flushing should be the default for removable media on user-friendly distributions, like swap partitions are)
Yes, but OS must tell the application how much of the operation is done
I was trying to say the opposite. Caching/buffering is what longers the lifespan and can speed system up
Zen kernel hasn’t even support for fat32 last time i used a usb.
Actually had to switch kernel to use it
