Applying a paragraph rewrites its page, but the page raster on screen
still has the old text until the page is rendered again. The textless
background and the editor went away on the frame the edit applied, so
for those frames the old text came back under the paragraph's new
outline, and then jumped to the new one.
The editor now remembers how it drew its text each frame. When the
edit that closes it is that paragraph's, the textless page and that
last look stay on screen until the page's new raster arrives, as
MoveBackground does for moved items. Any other edit, a zoom, or the
raster ends it.
