This was a slightly confusing bug report and patch, but I think this was
the proposed functional change:
diff --git a/lisp/net/shr.el b/lisp/net/shr.el
index 9c3740fccc..c05ac17521 100644
--- a/lisp/net/shr.el
+++ b/lisp/net/shr.el

((eq content-type 'image/svg+xml)
(when (image-type-available-p 'svg)
(create-image data 'svg t :ascent 100)))
+ ((eq content-type 'application/octet-stream)
+ nil)
((eq size 'full)
(ignore-errors
(shr-rescale-image data content-type
But I don't think that makes much sense: It doesn't really matter what
the content type is. The problem is that Emacs chokes on a particular
GIF file. To reproduce:
curl
"https://raw.githubusercontent.com/enphysoft/search-gmail-using-message-id/main/images/lgmid.gif"
> /tmp/lgmid.gif
emacs -Q /tmp/lgmid.gif
This initially hangs Emacs, but then it finally is able to display the
file... but Emacs uses 2GB worth of memory and 100% CPU.
