GID/UID not used everywhere, causing permission errors

[XanderStrike]

Expected Behavior

I should be able to specify GID and UID and have those be recognized and respected

Current Behavior

Console directories are sometimes created as root, sometimes as the specified user:

~/configs/emulatorjs $ ls -lh data/
total 48K
drwxr-xr-x 4 xander xander 4.0K Jan 24 12:16 atari7800
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 gb
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 gba
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 gbc
drwxr-xr-x 6 xander xander 4.0K Jan 24 12:16 main
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 n64
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 nds
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 nes
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 psx
drwxr-xr-x 4 xander xander 4.0K Jan 24 12:16 segaCD
drwxr-xr-x 3 root   root   4.0K Jan 24 12:15 snes
drwxr-xr-x 4 xander xander 4.0K Jan 24 12:16 vb

This causes the default file downloads to hang due to the following error in the console:

emulatorjs    | node:internal/process/promises:246
emulatorjs    |           triggerUncaughtException(err, true /* fromPromise */);
emulatorjs    |           ^
emulatorjs    |
emulatorjs    | [Error: EACCES: permission denied, mkdir '/data/gb/backgrounds'] {
emulatorjs    |   errno: -13,
emulatorjs    |   code: 'EACCES',
emulatorjs    |   syscall: 'mkdir',
emulatorjs    |   path: '/data/gb/backgrounds'
emulatorjs    | }

Steps to Reproduce

1. Run with a specified GID/UID
2. Click the button to download default files
3. Observe modal never completes
4. Observe error in console
5. Observe incorrect ownership

As a workaround, you I have been able to chown -R xander:xander data and have the default files complete downloading. Other tasks (scanning roms, downloading art) work properly after this workaround.

When docker mounts volumes like this in a tree it will be root owned on the parents. You can chown -R inside the container using exec to get the perms you need, but it won't survive upgrades.
