Incorrect behavio(u)r when checking against multiple trust lists - caching problem?

[bquinn]

Here's an example of a validator built in vanilla JavaScript using the c2pa JS library:
https://iptc.org/std/MediaProvenance/ValidationDemo/

We want to check against both the CAI "temporary certificate list" and our IPTC Origin Verified News Publisher list. So we need to call c2paIPTC.read twice, with two different settings objects.

The return values don't align with what we would expect, possibly due to some caching behaviour.

The workaround that we have used is to simply create two instances of the c2pa library locally, and use a different settings object with each.

But it would be great if we didn't have to do that and we could have only one instance of c2pa.js!

Please let me know if this doesn't make sense and I can make a better test case showing exactly what goes wrong.
