How to change HHead* properties for generated font?

[kayvanbree]

A little more backstory for this issue:

Everything works fine everywhere, expect in Chrome on MacOS. There our icons are all misaligned vertically like this:

When changing HHeaed Ascent to 448, the font will actually display correctly. We tried to change that settings in fontcustom.yml, but that did not work:

# The font's ascent and descent. Used to calculate the baseline.
font_ascent: 448
font_descent: 64

How can we set the HHead Ascent in FontCustom?

ATM we are trying to just fix the file on our Docker container:

RUN sed -i -e "s/font.ascent = options['font_ascent']/font.ascent = options['font_ascent']\nfont.hhea_ascent_add = False\nfont.hhea_descent_add = False\nfont.hhea_ascent = options['font_ascent']\nfont.hhea_descent = -options['font_descent']/" "/var/lib/gems/2.3.0/gems/fontcustom-2.0.0/lib/fontcustom/scripts/generate.py"

[edit]

This one actually works:

RUN sed -i -e "s/font_descent']/font_descent']\nfont.hhea_ascent_add = False\nfont.hhea_descent_add = False\nfont.hhea_ascent = options['font_ascent']\nfont.hhea_descent = -options['font_descent']/" "/var/lib/gems/2.3.0/gems/fontcustom-2.0.0/lib/fontcustom/scripts/generate.py"
