Drawn on the cell's morphing pill, the outline rode its shared bounds — so
collapsing painted it at the *expanded* cell's size and shrank it down, a
full-height outline flashing over a grid that no longer had full-height
cells. The same shape of mistake as the marker that used to cross the
outgoing month during a page turn.
It gets its own untagged layer, laid out where the collapsed cell actually
is, and fades in there. That is the only size it is ever true at.
