Description:
When opening the attached file, the initial loading of the file is crazy slow.

This is very likely because of the attached 5 fonts bloating that file to 1.7 MB in total.

The behavior is crazy on a macbook 2014 with

On my old Microsoft Surface Go it is loading really fast.

On my second mac (macbookpro 2018 with intel i7) it is loading "ok", but it is slow compared to other files. Only exception: embedded fonts.
