Hi, I wanted to submit this as a bug, but lately I keep getting in trouble for submitting bugs and then realizing I read the documentation wrong...
When I read the documentation for enriched-mode, I get the impression it is possible to save images embedded in a text/enriched document. And indeed, I can save an SVG image in the document. But for some reason when I open the document back up, the image is not displayed correctly. I tested that this behaves the same if I use "emacs -q".
M-x find-file ~/Scratch/enriched-test.txt
M-x enriched-mode
M-x eval-express (setq svg (svg-create 400 400))
M-x eval-express (svg-circle svg 200 200 50)
M-x eval-express (insert-image (svg-image (svg-circle (svg-create 400 400 :stroke "orange" :stroke-width 5) 200 200 50)))
[image is visible as expected]
M-x eval-express (setq enriched-allow-eval-in-display-props t)
[kill and reopen the buffer]
Instead of the image, I see only a small empty square. If I find-file-literally, I see that the image data is saved:
```
Content-Type: text/enriched
Text-Width: 70
<x-display><param>(image :type svg :data "<svg width=\"400\" height=\"400\" version=\"1.1\" xmlns=\"http://www.w3.org/2000/svg\" xmlns:xlink=\"http://www.w3.org/1999/xlink\"> <circle cx=\"200\" cy=\"200\" r=\"50\"></circle></svg>" :scale 1.7009009009009008 :transform-smoothing t)</param>circle</x-display>
```

synopsis: The extensible, customizable, self-documenting text editor
description: GNU Emacs is an extensible and highly customizable text editor. It is based on an Emacs Lisp
+ interpreter with extensions for text editing. Emacs has been extended in essentially all areas of computing,
+ giving rise to a vast array of packages supporting, e.g., email, IRC and XMPP messaging, spreadsheets, remote
+ server editing, and much more. Emacs includes extensive documentation on all aspects of the system, from
+ basic editing to writing large Lisp programs. It has full Unicode support for nearly all human languages.

That shouldn't stop you from reporting bugs. Closing a bug that is
not a bug is easy, and there's no shame in reporting a bug because you
didn't know something. So please keep reporting bugs whenever you see
something you think might be a bug.

I tried to reproduce this, but I see only an empty square at this
point. Are you sure you have all the steps of the recipe accurate and
without mistakes? (It definitely lacks (require 'svg) at least.)
When the image is displayed correctly, if you go to the image and type
"M-x describe-text-properties RET", what does Emacs show in a buffer
it pops up?

What do you see in *Messages* after you visit the saved file as
described above?

Sorry, I copied and pasted some bad code for you. This line
```
(insert-image (svg-image (svg-circle (svg-create 400 400 :stroke "orange" :stroke-width 5) 200 200 50)))
```
should read
```
(insert-image (svg-image svg))
```
to use the previously created svg object.

Thanks. This bug happened because enriched-mode was duped by strings
in image specs. Now fixed for the upcoming Emacs 30.
