KiCad 10 ERC doesn't complain about local schematic field changes (request for approval)

[mMuck]

Describe the bug
I'm a bit unsure with this and assuming this is a KiCad bug but I want to get this assumption approved from Part-DB users (because they have all requirements to approve this). A perhaps present limitation of HTTP libs could also be the source of this. Who knows(?). 🙂

I'm evaluating Part-DB as replacement for the KiCad Database Library feature. As this is an atomic part use one important thing is that changes to local values/fields must be detected by the schematic ERC. This is not "firing" always. Investigating. Changes to (some?) fields in Part-DB will trigger the ERC. (Timestamp based or field by field compare?)
Updating symbols in KiCad loads the new values but bulk updating schematics is a bit risky - this should be detected, evaluated and done part by part. There is a diff dialog in KiCad.

With the Database Library this worked as intended (when I tested it 🤔). A local changed field (in the schematic) got detected. A meanwhile changed field in the DB got detected. This was live, no caching. Very secure not to export wrong/outdated data into a BOM.

To Reproduce

1. Add a part from a Part-DB lib into a schematic.
2. Prove that the ERC is clean.
3. Change the part value or a field like MPN (which should be updated always in the lib source => Part-DB)
4. Check the ERC again.
5. ERC isn't complaining.

Expected behavior
ERC should complain about changes in every field which is imported from Part-DB.
