Yes, exactly.  There can be foreground-similar-to-background color
issues when mupdf + doc-view-mupdf-use-svg is used for certain, not
uncommon documents.

We can either document that issue in NEWS and docstrings, or we can
simply set "black on white" as default value of doc-view-svg-face which
would eliminate those problems (and match what we had in emacs 29 before
the face was introduced by Manuel Giraud) but would stop trying to apply
our emacs theme to the document, too.

I'd rather be conservative, use "black on white" as doc-view-svg-face
default value and document in NEWS and doc-view-svg-face's docstring
that one can style documents according to the emacs theme by inheriting
from the default face and not explicitly setting foreground and
background colors.
