Vertical scrollbar is added when email isn't confirmed.

[anviks]

Describe the bug
When an account doesn't have a confirmed email, a notification strip is shown, asking to confirm it. Its existence causes there to be a vertical scrollbar, which is really unpleasant, since I have to scroll to see discussion, submit and other buttons. Additionally, having a fourth scrollbar on the screen (in addition to scrollbars of kata description, solution and tests) makes it quite cumbersome to figure out, where my mouse has to be to scroll the outermost one.

To Reproduce

1. Have an account without a confirmed email
2. Start solving any kata (open any codewars link with "/train/" in it).

Expected behavior
Absence of scrollbar.

Screenshots
Here's a video where I demonstrate the effect of the redundant scrollbar and show that upon removing the email notification, the scrollbar disappears.
