v-v-curly, v-x-curly, maybe v-y-curly not applied in slab variant

[pv4]

If downloading "Iosevka Fixed Curly" or "Iosevka Fixed Curly Slab" or building a font variant for myself, the lowercase k/v/w/x/y look like at the picture.

Slab variants of k/w are still curly while v and x becomes straight. y becomes straight as well but it has a different shape so I'm unsure whether it should still be curly too (but I'd like it to).

• Your font version: 3.1.1
• Your font variant: sp-fixed (probably does not matter)

What's interesting, slab italic v doesn't seem to be affected by the bug (it's curly) while slab italic x is still affected.

Actually they are different but not very different...

Now the curvature is more observable.

Great, thank you! So fast!

The attached is the commit backport for 3.1.1 release. I did it for me but it might be useful for someone else.
