Commit 48ececc98 broke the statusbar in thumbnailbar-vertical mode. The statusbar is waaayyy too tall (~1020 px px tall in a window of 2160 px height, seems to start growing at a window height of ~315 px below which the statusbar is normal), as if the statusbar container is missing a necessary maximum height constraint. A horizontal thumbnailbar appears to avoid the problem by effectively sitting on top of the statusbar, squashing it to normal size. This is live-git gwenview on live-git plasma/frameworks, on qt 5.15.2, updated today (March 22), built from the gentoo/kde overlay live-git packages. Gwenview's current HEAD is f17af324e but bisection says 48ececc98 "Keep status bar below thumbnail bar" is the culprit.
Ah, we must have forgotten to explicitly constrain the statusbar's height to support that mode. Can confirm. Thanks for the bug report! Noah, can you take a look?
