fix: zoom from config is not applied

[ShGKme]

☑️ Resolves

• Zoom sometimes is not applied
• Electron's issue

How to test

1. Open talk (in dev mode is easier)
2. Change zoom to 120% by wheel/shortcut/settings
3. Open the config file manually
4. Change zoomFactor to 0.8
5. Reload the window (type rs to the console with npm run dev running)

Before

The window is small, but the zoom is big and unchanged

After

New zoom is applied correctly

Titlebar is not adjusted, when:

• open instance 1, zoom in
• close instance 1
• open instance 2, see bug
  if opening the same instance, can not reproduce

Instance of the same app or a separate instance with a new name?
