# Tagbottom against the one pane kind whose renderPane RETURNS EARLY. An image
# draws no body rows and no tagline of its own — the tag comes from the outer
# loop and so does the transient message row — so it is exactly the pane where
# "the tag moved" and "the message row moved with it" can come apart. Nothing
# in tagbottom.snap touches one.

# SPC t b: the tag leaves grid row 6 for row 30 and the glyph art slides up into the
# row it left. The style capture is the half a text grid cannot see — the
# tagline's chrome colours have to travel with it, and a tag row drawn in the
# palette of the cell art under it would read as part of the picture.

# precisely so an early-returning pane still gets one. With Tagbottom it lands

# ...and EXECUTE `Del` on that bottom tagline, which is the assertion the
# pixels cannot make: the middle click has to map grid row 30 to the image pane's
# TAG row rather than to a body row it has no body for. The image pane goes
# away entirely and the shell takes the whole window back.
# `@Del` locates the command text without depending on the image's metadata.
