Reproduction link

Steps to reproduce

Make (2*child-width + space/2) < Spacer width < (2*child-width + space)

What is expected?

Space changes from two columns mode to one column mode when two columns don't fit.

What is actually happening?

Space changes to L shape for a brief while, then after a while changes to one column mode.

Last Space child node do not have margin right which makes it to be L. Seems can be use flex gap instead. Need additional research since Row of changing cause many issue on horizontal gap.
