Mac app window does not remember set size, resets too small

Describe the bug
The MJML app (Mac) does not remember window size. Every time the window is closed or the app is relaunched, it comes back in a window that is roughly 800x580px.

The size is fine for the list of projects screen, however, the small size is maintained when you open a project so the coding area is extremely narrow and unusable until you manually resize the window again.
