own and group of the mount_point are changed to "root" after executing fuse-ext2 cmd in user account

[syvenwang7]

following command is executed in usr account "syven.wang"

mkdir -p mnt
#at the end of these commands, i checked own and group of mnt is still "syven.wang", not "root"
fuse-ext2 ext3_part mnt -o rw+ # after this command, own and group of mnt is changed to "root".

why did this happen and how to avoid this issue?

env:
centos 7
gcc 7.3
fuse-ext2 0.0.9 29
