In the navigator or editor either look at your breadcrumb.

Now hide the header/footer using the keyboard shortcut (Shift-Cmd-M on Mac).

Now navigate somewhere else or click on another file to edit.

Now show the header/footer

It just shows OrionContent and not very well.  You have to navigate or edit something else to fix it up

The layout of the breadcrumbs is being done by taking advantage of the offsetWidth attribute. The value of offsetWidth is always zero when the display is set to none, which means the calculations are incorrect when hidden.

Rather than using display: none to hide, we can use visibility: hidden instead, which results in offsetWidth continuing to be valid and the breadcrumbs showing properly when unhidden with the keyboard shortcut.
