And before you make some claim like "use keyboard", the UI includes these window elements for a reason. Top bar makes them less friendly to use: They're tiny and with top bar it's an aiming game instead of a quick way to do something with a mouse or a touchpad.
As an i3/sway user I don't greatly care about this because I already have things the way I like, but I understand the frustration of the OP.
Unfortunately people who design UI or produce specs are not power users so the end products have been losing utility at an incredible pace.
My personal favorite is an input field which clears its content once it loses focus. So when inputting an address on mobile you can't switch back and forth to copy different parts of it.
That info can be shown in the bottom panel, there is enough space there.
