Summary
This change adds back a working maximum font line height calculation method for macOS on fabric by using the common
UIFontLineHeightmethod that works for UIKit and AppKit. This is required for the correct calculation of the baseline offset for text having a line height greater than the text's font height.Changelog
[macOS] [FIXED] - Fixed the vertical text position in Fabric when setting a line height
Test Plan
Tested by running RNTester on macOS with paper and fabric (RCT_NEW_ARCH_ENABLED=1) and launching the TextInput example. As a regression test for iOS, the RNTester app was tested on iOS with fabric.
