Text inside segment not centered on iOS


I cannot get the text inside a segment header button to be properly centered on iOS device:

You can see the text is slightly on the bottom. I get the same behaviour on the iOS simulator.

However, text is properly centered on the browser:

I noticed this issue is also existing on the ionic conference app, so it is not specific to my case.

Please let me know if this will be fixed, or how I can fix it in the meantime.
