The viewport of the hashnode website has been affected when the bookmarks has been present and works fine when bookmarks bar is removed.

I have also tried to reply to an existing feature request that was opened a month ago but I think you might have closed that request. There are screenshots in the reply message that can help you identify the problem for viewport when bookmarks tab is enabled.

1. Another viewport problem (share icon in publishers blog)

When the bookmarks bar is enabled. There is no access to copy the permalink due to excess viewport problem. Hoping that you can fix these soon. I have attached the screenshots for the problem here.
