Window size is incorrectly restored to maximized dimensions instead of pre-maximized dimensions when closed while maximized

Some Software like Libreoffice or Telegram Desktop does not properly save and restore the window size/state when the application is closed while maximized.

When a window is closed in the maximized state, all standard applications are expected to restore the window to its original floating (pre-maximized) size and position upon the next launch.

Instead, LibreOffice etc stores the maximized screen dimensions as the window's last known floating size.

Consequently, when the application is opened again, the window appears in a floating (un-maximized) state, but with the full size of the screen (the maximized dimensions), instead of its original small size.

This behavior is extremely annoying, especially when the maximized state was achieved on a very large monitor (like a 4K display or external monitor), as the window becomes unusable on a smaller screen upon reopening.




STEPS TO REPRODUCE
1. Open a software like libreoffice (e.g., Calc or Writer)., blender, Telegram Desktop etc  
2. Resize the window to a small, custom size (e.g., 100×200 pixels) and ensure it is not maximized (floating state).
3. Maximize the software window using the title bar button. (The size is now the screen size, e.g., 1440×900).
4. Close the document/application while it is still in the maximized state.
5. Re-open the same software.
in libreoffice,  (if you open writer at first step, you must reopen writer and not Calc or Impress)


OBSERVED RESULT
The window size, instead of being displayed at its dimensions before maximization, is shown at the maximized dimensions, even though the application itself is not maximized and is floating.

EXPECTED RESULT
It should open in its pre-maximize dimensions.
This means that if the window is 320×300 in the first step and we maximize it, after closing and reopening the window, its dimensions should be 320×300, not 1440×900, which is my monitor's resolution.

ADDITIONAL INFORMATION
The problem is severe because I connect a large external monitor to my laptop. When I maximize a window on the large monitor and then close it while it's still maximized, the next time I open the same application when the external monitor is not connected, the window displays at the large monitor's dimensions but on my small laptop screen. This makes it difficult to resize and is frustrating.
