In commit e2f4351 "perf ui/helpline: Introduce ui_helpline__vshow()" the test for the browser used made ui_helpline__vshow() to be called only for the GTK browser. The TUI one then was not used and vfprintf(stderr, ...) was used instead, making the TUI scroll the screen instead of just printing on the last line. Fix it by doing the proper check, that is to call ui_helpline__vshow to be called for both the TUI and GTK browsers.
