Header mobile not showing menu and searchbox when username is too long

There is a problem with a long username and the header on mobile and the system is hidding the menu and the search box.

I solve it putting on the desktop.css.dsp changing
.desktop-user-panel.mobile .desktop-header-font.desktop-header-username {
font-weight: 600;

}
for
.desktop-user-panel.mobile .desktop-header-font.desktop-header-username {
font-weight: 300;
clear: both;
display: inline-block;
overflow: hidden;
white-space: nowrap;
}
