The vite-react config sets a value for tsBuildInfoFile to node_modules/.tmp/tsconfig.app.tsbuildinfo here:
https://github.com/tsconfig/bases/blob/main/bases/vite-react.json#L7
When two (or more) react projects in a monorepo extend from @tsconfig/vite-react, then only a single tsconfig.app.tsbuildinfo file will be created since package managers will deduplicate dependencies. This causes unexpected behavior such as the cache never be used as it's being overwritten by any sequential build from the other project.

Can be that this is fine for most users, so feel free to close if this is by design.
