[app] App cannot load properly when debugging is enabled in the build mode and DevTools is opened

Suspected Root Cause

• There may be some race conditions on loading caches

Workaround

1. Open the app with DevTools closed
2. Open DevTools
3. Setting a breakpoint at the first inner statement of loadCache() in cache-bundle.js
4. Clear the storage of the app in Application tab
5. Load the app
6. Wait for a halt at the breakpoint
7. Restart the app from the breakpoint
