it's adhering to the default page width, it looks off though due to the offset of the side canvas. I'll make some adjustments here.
For now, try this in extra.less:
Code:
.p-staffBar-inner {
max-width: 100% !important;
}
.p-staffBar {
position: relative;
z-index: 2;
}
.xb-page-wrapper {
z-index: 1;
}
