case + calt does not replace -> with arrow

[VasiliyRusin]

Describe the bug
First of all. I'm not sure what it's a bug, but it looks pretty bad. And according to the demo from the website, it should be nicer.

If I use font-feature-settings: 'case' 1;, I lose alt case, but if I didn't use it, my symbols jump with a different case.

UPD.

Now I absolutely sure that it's a bug. Most features of 'calt' work as expected with font-feature-settings: 'case' 1;. But arrows not. The demo was updated.

To Reproduce
Just watch demo.

Expected behaviour
I hoped to get both of these. Fixed vertical position and alt case.

Environment

• OS: Windows 10 1809

• Chrome and Affinity Designer. But I suppose that it will be on any app.

• Current version from css file.

font-feature-settings: 'case' 1; will turn on case feature only. If you need calt you need to write font-feature-settings: 'case' 1, 'calt' on;

First of all, calt is on by default. But even if I on it, it won't work.

@VasiliyRusin @rsms
I see the problem: In lookup 39, uni2192.case is built up with uni002D.case and uni003E, where the latter glyph should be uni003E.case. This mistake also happened in other arrow combinations.
