How to stop entire VSCodium/VSCode window from being OOM killed in Fedora when it's better to kill the command in the integrated terminal that's the cause of high memory usage?

It's acting as if memory.oom.group is set to 1, even though it's not:

dullbananas:~$ cat /sys/fs/cgroup/user.slice/user-1000.slice/user@1000.service/app.slice/app-gnome-codium-158608.scope/memory.oom.group 
0
dullbananas:~$ cat /sys/fs/cgroup/user.slice/user-1000.slice/user@1000.service/app.slice/memory.oom.group 
0
dullbananas:~$ cat /sys/fs/cgroup/user.slice/user-1000.slice/user@1000.service/memory.oom.group 
0
dullbananas:~$ cat /sys/fs/cgroup/user.slice/user-1000.slice/memory.oom.group 
0
dullbananas:~$ cat /sys/fs/cgroup/user.slice/memory.oom.group 
0
dullbananas:~$ cat /sys/fs/cgroup/memory.oom.group 
cat: /sys/fs/cgroup/memory.oom.group: No such file or directory
