Avalonia 11.2.4 Version Problems

[OmerFarukAkyapak]

The toggle button on the right side of the ComboBox and SettingsExpander is misaligned. When I try to use a SymbolIcon inside a button, it also becomes misaligned. These issues were not present in .NET 8, and everything worked fine with the same code. In Avalonia, up to version 11.2.0 with .NET 9, everything works without any issues. However, the problem starts in the latest release (11.2.4).

I think there is a discrepancy with the latest version.
