Alacritty in tiling mode has padding not present in floating mode

[d4wns-l1ght]

Body

Steps to reproduce:

1. Open Alacritty as the sole window, in tiling mode (Alacritty config window.startup_mode should be "Maximized")
2. Switch to floating mode (note that the window remains the same size)

Expected result: There is no change in the padding at the bottom of the screen
Actual result: There is a bar/line worth of padding at the bottom of the screen, but it disappears when Alacritty is made a floating window. The padding does not appear in floating mode no matter the size/ratio of the Alacritty window. Switching between floating and tiling mode makes the padding toggle even though the window is the same size.
Note: I'm aware this probably has something to do with Alacritty adding padding when the window is not exactly the right height. The notable part of this behaviour is due to the fact that the window is the same size before and after the change.
