2nd, 3rd and 4th hyphens too thin when chained in 28.0.0+

[rhenescu]

In 28.0.0+ the 2nd, 3rd and 4th hyphens in a chain appear too thin vs the rest (3rd row and onwards, zoomed in 200%):

Also, the 1st hyphen is slightly thinner than the 5th+ (visible in the image above when zooming in even more, without smoothing). Maybe it's related to the changes in #2100? 27.3.5 and lower are not affected by this.

You can try the unhinted version, which should be more consistent.

I really hope @lemzwerg could allow defining CUSTOM scripts (with CUSTOM alignment zones, and the glyph IDs to measure them) in TTFA, which will be very helpful for handling symbols.

I would be glad if you could provide a patch. Right now, I'm working on completely different projects, not taking any time for TTFautohint...
