[bug] Rendering issue when scaling \uf444 with Menlo and mapped Symbol Nerd Fonts

[broeknbytes]

Describe the bug
When rendering the glyph \uf444 and centering vertically the dot gets chopped in half. Issue is not there when aligned top/bottom, and also issue is not there when starting with --config NONE. I'm hoping this is an error on the user part that can be easily solved.

To Reproduce
Print \uf444 vertically aligned top, bottom, middle:

printf "\e]66;n=6:d=7:v=0:w=1;\uf444\a\e]66;n=6:d=7:v=1:w=1;\uf444\a\e]66;n=6:d=7:v=2:w=1;\uf444\a\n"
