Trying to reproduce the issue is a great first step! I use https://crossbrowsertesting.com/ - it's a great service for testing websites on many different device/OS/browser combinations. (I can not imagine doing web development without such a service - or a huge local device lab.)

I'm a web developer. The issue has been bugging me for years - I coded elaborate workarounds, and I hope that there will be a real solution for the future.

I submitted the issue description including exact pixel measurements of the cross-OS difference of one case, provided three test pages, eight screenshots, and links to three browser issue reports. I should (and have to) leave the rest - including further investigations and including the solution - to the CSS WG and to the browser vendors.

I need consistent glyph positioning across OSs, browsers, and devices - no matter whether the font and it's metrics can be considered unusual or not 😀
