New Modal window stretch if a single line text edit inside has lot of chars

[itsNiccoloSabatini]

Bug description
if inside the new Modal window there is a TextEdit::singleline with more char than the length of the Modal it will grow to "contain" the text, but is kinda awkward in fact once it grows it can't go back to normal size.

To Reproduce
Steps to reproduce the behavior:

1. open a modal that has inside a TextEdit::singleline.
2. write inside the TextEdit until the window starts to grow and reach the end of the screen.
3. select all the content of the TextEdit and erase it's gonna stay the same enlarged length.

Expected behavior
The expected behavior should be that the Modal window won't grow to follow the text inside the textbox, it could also be a good idea to implement max_width and max_length (to set a max size for modal windows) and a fixed_width and fixed_length (to fix the size of a modal window) for Area of Modal.

Suggest taking a look at hydra's egui_tabbed example, where he used taffy to solve this issue per my understanding:

I agree with @itsNiccoloSabatini that it's a bug and shouldn't resize in the way it does. My issue was primarily focussed on having the text entry box resize with it's parent container, and I was able to solve that with taffy:

My workaround was here, but obviously involves using egui_taffy: https://github.com/hydra/egui-tabbed-document-ui-example/blob/073d94ee85ea9efa0c92cf9a713986122075bb6f/src/app/app_tabs/new.rs#L162-L181

Pretty sure this should be solved by #5640, can you try using egui from that branch to see if that fixes it?
