Finally managed to track down one of my Pis and got LibreElec nightly installed onto it. This does indeed fix it for all new stuff added to the database the fix has been applied. However, it does require a "repair database" to fix old entries. Therefore, we have two options:

• Detect the update, trigger a repair database on the movies library (painful for users)
• Detect the update, perform a database migration to update old entries (painful for us)

I'll need to think more on that, it'll probably happen in a separate PR, but I'll leave this open for the moment in case @oddstr13 has opinions

Still syncs episodes for me in Kodi 20.2, so that is sufficient for me.
