A span asks a share child twice in one draw: in the room, whose answer
its slots rest on, and in the decided slot, whose cross-axis answer it
reads. The record keeps only the second question, so a local redraw that
found that answer unchanged never told the row that the first had --
seed 946 at depth 6, where emptying a fixed-height column turns it from
a share into a fixed width as wide as the row. A widget its parent asked
more than once in one draw now defers to that parent, like one whose
declared length changed. Pinned as
unsettled::emptying_a_column_the_row_asked_twice_asks_the_row_again.
