  Recently, Pandya et al. (2023) argued that the shapes of dwarf galaxies in
JWST-CEERS observations show a prolate fraction that rises from ~25% at
redshifts z=0.5-1 to ~50-80% at z=3-8. Here we suggest that this apparent
change could result from a surface-brightness bias, favoring the detection of
edge-on disks at low-luminosities and high-redshifts. Changing edge-on
projections with an axis ratio of 10 to a face-on orientation reduces their
apparent surface brightness by 2.5 magnitude per arcsec$^2$ and could shift a
substantial fraction of the observed galaxies below the detection limit.
