Inferred tasks disappear from project graph view after changing nx.json

[DanielGiljam]

Current Behavior

If I open the project graph view for, e.g. nextjs-app (nx show project nextjs-app), then at first the inferred tasks show up there nicely.

But if I then go ahead an make some innocent changes to nx.json and hit save, the project graph view reloads, and the inferred tasks are gone.

After shutting down the project graph view (Ctrl+C) and starting it again, the inferred tasks show up again.

Expected Behavior

After making changes to nx.json, the inferred tasks should still be there after the project graph view has reloaded.

Steps to Reproduce

1. Run pnpm nx show project nextjs-app.
2. See how when the project graph view has opened up in the web browser, the inferred tasks show up there.
3. Make some change to nx.json, e.g.

   {
     "plugin": "@nx/js/typescript",
   - "options": {
   -   "typecheck": {
   -     "targetName": "typecheck"
   -   },
   -   "build": {
   -     "targetName": "build",
   -     "configName": "tsconfig.lib.json",
   -     "buildDepsName": "build-deps",
   -     "watchDepsName": "watch-deps"
   -   }
   - }
   }

4. See the project graph view reload, and the inferred tasks now being gone.
5. Shut down project graph view (Ctrl+C).
6. Start project graph view again.
7. See how when the project graph view has opened up in the web browser, the inferred tasks show up there again.
