StatusStrip button next to SizingGrip is now missing

### .NET version

10.0 Preview 6

### Did it work in .NET Framework?

Yes

### Did it work in any of the earlier releases of .NET Core or .NET 5+?

This works in .NET 9, and it was working fine in .NET 10 Preview 5

### Issue description

I have a `StatusStrip` in my app, and at the bottom right there are some zoom-related controls and then the sizing grip.

Since .NET 10 Preview 6, the last of my buttons, which performs a Zoom In operation, is missing.

I'm guessing it's related to #13620 by @KlausLoeffelmann, but it's also similar to #11208.

### Steps to reproduce

Launch Paint.NET using .NET 10 Preview 6 (I can provide binaries, and/or access to the repository here on GitHub)

It should look like this:

Instead, it looks like this. Note that the button with the hourglass and plus sign is missing, which is the "Zoom In" button:
