Inconsistent spacing between rows on different results screens, when using a custom STTNUM font

I had originally posted about this on the SRB2 forums, but I didn't realise there was place on GitLab where I can post issues! Seems more suitable here, despite it not being the biggest issue in the world.

I've noticed during my experiments that if you use a custom STTNUM font that is larger than the standard size (11 pixels tall), then it creates a larger gap between rows during the end of stage results screen. In the examples below, the STTNUM font size in the custom HUD is 14 pixels tall.

However, this effect doesn't seem to apply to special stages...

Is there a reason why these would act differently? And could they be standardised (preferably like the special stage results screens)?
