* Electron version: 8.0.0
* Operating system: Linux - Fedora 31 - Kernel 5.4.13-201.fc31.x86_64

### Expected behavior
The local store should persist items even though the app is terminated as soon as the item was added.

### Actual behavior
If the app is terminated in less than 2 seconds after an item is added to local storage, the value is not available after the app is reopened.

### How to reproduce
1. Create a new electron app 
(I used the quick start from the website git clone https://github.com/electron/electron-quick-start)

0. Run the app using `npm start`

0. Run a JavaScript code that adds a new key/value pair to localStorage
````
localStorage.setItem("my-key", "my-value")
````

0. Within 3 seconds, terminate the app (killing the process or pressing Ctrl + C)
NOTE: If the app is closed properly (pressing Alt + F4 or click on the "X"), this issue does not occur.

0. Run the app again

0. Check for the localStorage items
````
localStorage.getItem("my-key")
````
Or in the Application tab from Developer Tools.

Both cases are not available neither the key nor the value
