menu centering not relative to screen dimension

HI, Hi thank you for the new functionality which allows you to align the menu in the center of the screen, thank you for taking the time to take a look at it,

as I quickly tested it, I wanted to give you feedback, Well, it turns out that I noticed that the position of the menu took into account the thickness of the panel, which means that the menu is not in the center of my screen but in the center of my screen minus the thickness of the panel. my panel, would it be possible to correct this?, for someone who has a panel with the original theme (full), this could go unnoticed, but since the theme of my panel is island, it is very outstanding,

THANKS.
