Maximized window width and long swipe gestures should respect horizontal margin

[lost-melody]

Describe the bug
Now Super+= can increase the window width until screen_width - 2*horizontal_margin, and Super+F sets the width to screen-width - 2*window_gap. But when the margin is greater than gap (in my case, margin=64 and gap=20) it is incorrect.
And if I switch to the maximized window which is off screen quickly (without showing the minimap), its width screen_width - 2*gap will be decreased to screen_width - 2*margin, otherwise the width remains unchanged.

Plus, when I swipe the view quickly, the first or last window will "snap" to the screen edges, with a gap of window_gap but I think this should be horizontal_margin. Also when I switch the focus mode from EDGE to DEFAULT it will snap to screen edges with a gap of window_gap instead of horizontal_margin.

To Reproduce
Steps to reproduce the behavior:

1. Set horizontal margin to 64 and gap between windows to 20.
2. Maximize a window by Super+F (its width would be screen_width - 2*gap, while I believe it should be screen_width - 2*margin).
3. Switch to other windows until it is off screen.
4. Switch back to the window quickly before the minimap showing (its width would be decreased to screen_width - 2*gap).

Expected behavior
Horizontal margin and vertical margin define the maximum view region in the screen so I believe the active window should never exceed it.
