I haven't yet rebuilt with --enable-checking='yes,glyphs', but I just made a new, perhaps relevant, observation: after step 8 of the recipe, i.e. with point at the end of the line but hscrolling undone, if I move the mouse pointer to a position that pops up a tooltip (i.e., over a tool-bar icon or a mode-line element), then with x-gtk-use-system-tooltips set to t nothing changes but with x-gtk-use-system-tooltips set to nil, the hscroll is restored, like with `M-x' before `C-g', and the hscroll stays when I move the mouse so that the tooltip vanishes, but if I then type `C-g', the hscroll is undone again (and point remains at the end of the line, out of view).
