[window-state] Y Axis Drift

Using Pop!_OS 22.04 X64

### What I did
-use basic tauri app example
-add window-state plugin

### The Problem
When the app is closed and then re-opened, the Y coordinate drifts +37 pixels. I thought this was a very strange number, but suspected what it might be. I took a screenshot of the app and opened GIMP, and sure enough, the title bar of the app is exactly 37 pixels in height. I'm not sure if this is a Linux issue but it seems the window-state plugin is not accounting for the title bar in some way, resulting in a compounding 37px drift every time the app is opened.
