Game Scanning not completing

[molnara]

Describe the bug
Using the new game scanning feature, it seems to scan indefinitely. If I look in folder /fat/.cache/WebMenu/games/media/fat/games I can see a file *.jsonl growing and then shrinking over and over. It reaches around 13,000 games before it starts over.

Describe your setup

• WebMenu Version: v0.5.0
• MiSTer Version: v200608

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Settings'
2. Click on 'Scan Folders'
3. Expand folder to games location '/media/fat/games'
4. Click on 'Scan' next to a console (I was scanning SNES)
5. Scans forever

Expected behavior
Should complete scanning.

Web Browser:

• OS: Windows 10
• Browser Firefox
• Version 77

Additional context
All my roms are organized using Smokemonster's Packlist database. These are all close to 100% complete, so very large rom collections. Also many duplicates, ie. Game Series Collections

Could you try to scan a smaller folder first (i.e. ATARI2600) and tell me if it does the same thing?
