If the option "Show sort header in icons modes" is enabled, and you open a new tab the header is not present in the new tab. The space where the header should be is occupied by a blank space.
Doesn't matter what view mode you're in (list, details, power)
I cannot reproduce this. Which display mode is the original tab, and which is in the new tab when it opens?
Both are in list view.
Maybe some other option that is enabled/disabled is causing it to happen. But finding that option could be hard in the sea of options.
