💖 Thanks for opening this pull request! 💖

Here is a list of things that will help get it across the finish line:

• Run yarn lint locally to catch formatting errors. This will fix some errors automatically, commit and push any changes.
• Run yarn test locally to catch errors. This ensures all components still behave as they should.
• Run yarn start to run the doc site locally and try a few pages, ensuring everything is in good working order.
• Include tests when adding/changing behavior.

We get a lot of pull requests on this repo, so please be patient and we will get back to you as soon as we can.

@layershifter You welcome. I will check this out.

@layershifter updates have been made to the PR. A scroll bar still appears and disappears at a given size. Going through the current implementation I discovered the same behavior.

@codrex thank you for your effort there, I really appreciate it 👍

However, I opened #3465 with the detailed description why I want to do that changes. Sorry for the late response, I wanted to hear the opinion from the team that uses SUIR very long time.
