Webstorm update 2024.3 broke schema discovery in excluded files

[reckter]

Describe the bug
After updating to 2024.3, graphql didn't correctly pick up the api schema, resulting in no types found, and lots of errors.

Setup:
We have a monorepository with one schema package that "compiles" a bunch of graphql files into one api.graphql file.
located in /packages/schema/build/graphql/api.graphql

In our graphql.config.yml, we mention this file directly:

schema: packages/schema/build/graphql/api.graphql
projects:
  frontend:
    documents: "apps/frontend/**/*.{graphql,js,ts,jsx,tsx}"

This worked without problems in earlier webstorm versions.
If I move our api.graphql file outside of the build directory it still works as it did before.
The build directory is on the .gitignore and is marked to ignore in the IDE

Operation system: macOS 15.1
IDE name and version: Webstorm 2024.3
Plugin version: 243.21565.122
