TYPO3 Core

Hi,

I found a new problem with the top bar of the typo3 backend, so the problem is when the name of the user is too long, or when using a Super User with a long name, I add a screenshot describing the problem, as is visible the top bar has been at two lines in case of the name is very long.
This is a regression from the previous version 10.

As a solution, I just make a small change in the CSS

.t3js-scaffold-header{
    flex-direction: column;
}
