I knew nothing about this before, but apparently the use of SVGs to lay out
text + images is one recommended way to produce fixed-layout EPUBs:
https://kb.daisy.org/publishing/docs/fxl/svg.html

Examining a fixed-layout EPUB produced by LibreOffice in Sigil, I see that text
following an image becomes part of the SVG.

Regarding Kindle support, your experience makes sense as the guidelines as of
version 2026.3 say "<svg> with <text> is not supported":
https://kindlegen.s3.amazonaws.com/AmazonKindlePublishingGuidelines.pdf

It seems this would be better as a request to Amazon to expand their support.
They have improved SVG support over the years as I found a discussion from 2018
where the guidelines were quoted as saying "Enhanced Typesetting does not
support SVG images".

A report should deal with a single issue, so I am changing this to be about the
centering as likely we want to retain the SVG-based layout.
