Line Height Issue on latest master

Describe the bug
I noticed that when building the latest master of macvim, font line-heights get weirdly messed up.
I am on macOS Mojave - 10.14.6

Normally I run off the stateful-render branch, but was trying to rebase master into it when I came across the bug. So I tried building master manually to see if it reproed, and it did indeed.

Edit Notes:
I build via github, via this lil custom build script:

#!/bin/bash
make clean
make distclean
./configure --with-features=huge --enable-terminal --enable-rubyinterp --enable-python3interp --enable-perlinterp --enable-cscope --enable-rubyinterp --with-ruby-command=/usr/bin/ruby
make
rm src/MacVim/build/Release/MacVim.app/Contents/Resources/MacVim.icns
cp ./MacVim.icns src/MacVim/build/Release/MacVim.app/Contents/Resources/
open src/MacVim/build/Release

Output from reading org.vim.MacVim:
