I can see a teeeeeny tiny misalignment at 90%, but nothing nearly as severe as previously screenshotted…
Anyways, the left part is styled with line-height: 24px and I’d assume that font hinting is causing this to be scaled differently then a straight up height: 24px. In fact, applying height: 24px to the element in the inspector results in both links having the same height even after scaling…
