[bug] [v2] when enable unstable feature，the window just can resize from top bar.

[Xiaobaishushu25]

Describe the bug

when enable unstable feature，the window just can resize from top bar.

Reproduction

add this to Cargo.toml: tauri = { version = "2.0.0-beta", features = ["unstable"] } and run,you will find you just can resize the window from top bar even you have set the window config:resizable is true;
this is when i did't enable unstable feature:

stable.mp4

then i have not change any other config and code, just enable unstable feature

unsta.mp4

because i need to use https://beta.tauri.app/features/window-state/, i need to get the window by: app.get_window("main").unwrap() , It seems that the unstable function must be enabled to achieve this.

Expected behavior

[Xiaobaishushu25]

and i also find another problem, it doesn't seem like the problem was caused by tauri, but it does happen when the enable unstable feature :

stable-echarts.mp4

unstable-echarts.mp4

It's all the same operation: minimize the window and restore, but when enable unstable feature , the rendering of echarts is abnormal. It seems that the size of its container has been restored normally, but the chart did not obtain the correct width and height. This doesn't seem to be a problem with tauri, but if it's not enable unstable feature, there won't be such an abnormal situation.
