This repo gives a reproduction of the issue described here: import-js/eslint-import-resolver-typescript#94
tsconfig.json has a references entry, which includes two other tsconfigs.
A path alias is set in tsconfig.app.json and it works: editor go-to-source, dev server and build are all successful.
However, eslint-import-resovler-typescript does not seem to evaluate it.
Note that when specificly including all tsconfig.*.json files as projects it does work. (Uncomment line 14 in eslint.config.js to see the issue disappear).
But this is not ideal when creating a shared config.
