This is a clientside bug from Navigation refresh part 1. Because you can go through profile in Article, it's not listening for the text size change in settings.

Thank you for tagging this task with good first task for Wikimedia newcomers!

Newcomers often may not be aware of things that may seem obvious to seasoned contributors, so please take a moment to reflect on how this task might look to somebody who has never contributed to Wikimedia projects.

A good first task is a self-contained, non-controversial task with a clear approach. It should be well-described with pointers to help a completely new contributor, for example it should clearly pointed to the codebase URL and provide clear steps to help a contributor get setup for success. We've included some guidelines at https://phabricator.wikimedia.org/tag/good_first_task/ !

Thank you for helping us drive new contributions to our projects <3

I want to work on this project. can anyone guide me on how can start contributing on it?

@Gsaurav641: Please do read https://www.mediawiki.org/wiki/New_Developers#Communication_tips and don't ask for assignment - thanks a lot.

Fixed on 7.6.2 (4449)

Thanks for working on this one @Crozariodev, @GOlson-WMF and @Tsevener! Looks good
