Here is the HTML file:

It is valid HTML file. Check it on https://validator.w3.org/nu/#file
Problem is shown on this picture:
https://gnu.support/images/tmp/2022-10-08/Screenshot-2022-10-08-16-14-27-712668711.png
the picture in the table row does not align with its top with the text
on the right in the right cell. If there is much text in the right cell,
the picture moves even more down.
It would be good to have proper eww table rendering.

The Emacs display engine doesn't support flowing text around images --
an image is just one very big character, so you can't have two lines of
text next to an image.
So shr just puts all images in tables after tables.
Closing.

Closing the bug does not make it less bug. Please do not close.
I have researched today and found that Telega can splice images and
thus show very nicely image and text next to each other, including in
multiple lines.
Would that not be good improvement in Emacs to be able to display
image and text side by side?
I suggest looking into Telega, as the trick that author uses is
splicing images. I can see chars side by side to the image and image
appears very correctly and is scrollable.

telega-ins--image-slices is a byte-compiled Lisp function in
‘telega-ins.el’.
(telega-ins--image-slices IMAGE &optional PROPS SLICE-FUNC)
Insert sliced IMAGE at current column.
PROPS - additional image properties.
SLICE-FUNC - function called after inserting slice. Called with
single argument - slice number, starting from 0.
I do not understand the code yet. It would be nice if somebody can
help on this to become able to construct image and text on the side.

Telaga can do that because it uses fixed-width characters, so everything
aligns nicely. As far as I know shr uses veriable-width characters so
the same is much harder to do in shr, not to mention that telaga only do
this for the profile image on the beginning of a line, whereas shr needs
to handle complicated layout, like tables.

Telega cuts images horizontally for the height of characters. Using
that method of image display is possible to handle tables with images
inside.
