Accessibility Large Text option causes cursor shift on full screen open file dialogs

[Niccolò Gallarati]

**** The bug is not necessarily related to xorg but could be Gnome related ****

When Large Text option from the Settings > Accessibility > Seeing panel is enabled, a bug is occurring on fullscreen file selection dialogs (i.e. LibreOffice Draw "Open..." dialog or Image Viewer "Open" dialog)
The clickable areas (i.e. buttons and files list) are shifted down by around 16 pixels so that in order to select a particular object the mouse upper cursor point must be above that object.
If Large Text option is disabled, the dialog clickable areas are just fine.
Non-fullscreen open file dialog windows (i.e. Text Editor "Open" dialog) are working fine with the Large Text option enabled - the bug is occurring only with full screen, non resizable ones.
The bug is still there when all updates available in Software Updater as of today are applied.

How do you make the file picker dialog "fullscreen"? Do you mean that it is "maximized"?
I was able to see this bug once when the dialog appeared maximized, only on the Xorg session, but since I've resized it down I can't reproduce anymore and I don't know how to maximize it again.
