Inconsistency in tabular vs. proportional oldstyle numeral 4

I noticed what seems like an inconsistency in the oldstyle variants of the numeral 4. In the tabular version the angled stroke is noticeably bowed outward, while in the proportional version is it very nearly straight. For a quick illustration, see the attached file.
I'm not entirely sure this is a bug, but the difference in styles was enough to catch my attention.
Given that this project has been unmaintained for years I would not expect this to get fixed.
I did just check this in the Libertinus fonts fork and confirmed the issue. I agree the old style glyph shape should not change based on the horizontal alignment feature +tnum vs. +pnum. I've opened a corresponding issue report and plan to fix this there eventually.
This is a blast from the past :) Thanks for carrying the issue over to the Libertinus fork.
