Description
### What happened?
`ACustomCaptionWindow` lacks proper integration with Windows 11.
_(note: the screenshot is taken from Windows 11 machine with 200% system scaling)_
- The 'maximize' icon should be slightly rounded on Windows 11.
- Windows 11 features a dropdown with options when hovering on the 'maximize' button. `ACustomCaptionWindow` lacks this feature.
The issues are not present on regular `AWindow` windows.
### Relevant log output or stack trace
```shell
```
### Steps to reproduce
```bash
1. Open any application based on `ACustomCaptionWindow` on Windows 11.
2. Observe the difference with other applications (including 3rdparty).
```
### Affected Platforms
Windows
### Link to build, i.e. failing GitHub Action job (if any).
