So, I'm understanding this correctly — the problem in your example is that in the third line below, inst is not a CallNode and therefore the bar call is not found? That's quite an easy mistake to make. As you're on a roll, this might be worth doing a ql-for-ql query for?
const Foo = require("foo");
const inst = new Foo();
const result = inst.bar();
Also, the check asks for a change note, but I think you can disable that.

Gets a TP for CVE-2021-46704
Evaluation was uneventful.
Consider the below.
This will not flag the below:
Because
DataFlow::moduleImport("foo").getAnInstantiation().getAMethodCall*()is restricted to the typeDataFlow::CallNode, even if we take 0 steps through the transitive closure.
