Does disable_cleanup work with unpacked extensions?

I’m trying to keep the indexedDB data after uninstalling the app, so after re-installing the app I can retain the saved data from my previous install.

I tried building the app with the disable_cleanup flag in the manifest, then after restarting the app once, I uninstall it and reload the unpacked extension. The indexedDB data doesn’t load when I start the app.

I also noticed that a folder for the app does not get created or deleted in the %localappdata%\Overwolf\Extensions folder when I load or uninstall an unpacked extension.

How can I go about testing if the disable_cleanup flag can be used to save the indexedDB across re-installs?
