Auto sized Window does not get updated when app window is resized larger

[msparkles]

Describe the bug
When having a auto sized Window, texts get squished when the app window is small (see screenshots).
This is to be expected. However, it does not return to normal after the window is resized larger.

To Reproduce
Steps to reproduce the behavior:
0. This is just speculation, didn't actually test if this reprod would work.

1. Make a auto_sized() Window
2. Put in some texts
3. Resize the application window smaller that the text is forced to wrap
4. (Maybe you need to be on Linux/X11 too?? we can't verify this ourselves)
5. Undo that resize, i.e. make the window larger
6. The text doesn't get their wrapping, well, unwrapped

Expected behavior
For it not to do that, not to wrap the text even though there's enough space.

Screenshots

Desktop (please complete the following information):

• OS: Arch Linux on X11
• Egui Version: 0.27.1

I think this bug was introduced by #4199

Potential fixes:

• When clamping window size to the viewport size we should not store it in the state.
• Ognore the stored size for auto-sized windows

I think using ScrollArea will help.

        egui::ScrollArea::both()                                                      
            .show(ui, |ui| {                                                          
                ui.horizontal_wrapped(|ui| {                                          
                    ui.label("test test test");                                       
                });                                                                   
            });

This has nothing to do with #4199.

#4199 limits the maximum size to screen_rect(), and has no effect elsewhere.

However, #4199 has significant limitations, so for future development, I will submit a Pull Request with minimal limitations.
