When the left sidebar is unpinned/collapsed but temporarily expanded, it interferes with the Display module Info view.
Repro steps:
1) Collapse the left sidebar with TAB or by clicking its left edge.
2) Switch to one of the Display module modes: press E, C or N
3) Enable one of the image Info display modes: press I
4) Hover over the sidebar's left edge so it expands
The sidebar partially covers the image area, but not the Info overlay which renders over the top of the sidebar, creating a visual mess.
Incredibly, when I had an Adobe Support operative look at this last night, they told me this is working as designed. I really hope that was a mistake.
