Wanderlust/2.15.9 (Almost Unreal) SEMI-EPG/1.14.7 (Harue) FLIM-LB/1.14.9 (Gojō) APEL-LB/10.8 EasyPG/1.0.0 Emacs/27.2 (x86_64-pc-linux-gnu) MULE/6.0 (HANACHIRUSATO) |

1. Save the attached TIFF file as attach.tiff.
2. $ emacs -Q attach.tiff &
3. Notice that the image contains multiple frames.
4. Type `f' (image-next-frame).
Expected behavior:
Switch to the next frame. Emacs 27 works as expected.
Actual behavior:
Wrong type argument: number-or-marker-p, nil
This seems to be a regression introduced by the following change:

Speed up animation of non-displayed images

once -- this avoids recomputing the image on every iteration when
the image is not displayed (bug#47895).
