Does this need a specific browser? When I try a unit page at 950px wide without this fix, I don't see any gap.

I'm having trouble reproducing this, as well. (Firefox, here.)

[PKulkoRaccoonGang]

@ihor-romaniuk I also couldn't reproduce this issue. Also, I see that you added max-width: 100%; to the sequence-navigation-tabs CSS class, but I couldn't find it through the developer tools.

[ihor-romaniuk]

I also can't reproduce this bug. Probably it has been fixed or required additional steps to reproduce.

I propose to close it for now as a not relevant.

@PKulkoRaccoonGang we can find this class through the developer tools:

[arbrandes]

Alright, let's close it for now, then. Thanks!
