Description

There are 2 samples below, captured in Windows 10, latest PHPStorm. Both fonts are 14px, semibold, TTF-AutoHint version.

V7.3 Image

V7.2

Image

In V7.3, when I type "=" and next ">", "=" symbol remains the same. In V.7.2 distance between lines of "=" increases to perfectly match arrow end.

VSCode and Sublime text has the same problem.

P.S. Thanks for great coding font!

Contributor guide

Research direction
Examine the font's hinting instructions for the equals sign and arrow glyphs in the TTF AutoHint version, then adjust the links and adjustments to correct ligature alignment when hinting at small sizes.
