USB Drive still accessible from vault after ejected via sys-usb

I just noticed that after assigning a usb drive to vault, copying files, searching the usb drive in vault CLI, if I detach (eject) the usb drive from vault, it is still attch to it, I can perform RW on the usb drive from vault qube it is not the awaited behavior, isn’t it ?
Ho, and just tested, I can still access the drive via vault qube after attaching it to personal qube !!??
Using Qubes 4.2.0 with kernel 6.6.2-1.fc37, I was wondering if somebody else has the case, and if it’s a bug.

I can perform RW on the usb drive from vault qube it is not the awaited behavior, isn’t it ?

Info needed. Please do the following steps:

1: Mount the drive in A (a domU)
2: Eject the drive via ‘Qubes Devices’ tab
3: Save ‘hello world’ in a .txt file to the same drive from A.
4: Mount the same drive via the ‘Qubes Devices’ tab in B, a different domU.

Do you see the data you wrote in 3) after 4) in B?
