Caption font reset

[senthilmm]

Testphase=phase-III

Caption label and text font is reset to serif.

MWE-CaptionTest.zip

Testphase=phase-II gives the correct output.

Thanks

Sorry, but the caption package is currently not supported. See e.g. #84 and also the status list https://latex3.github.io/tagging-project/tagging-status/

Thanks. Much appreciated.

You could try the following. It is not perfect (e.g. the label is not tagged as Lbl) and not much tested, so can perhaps break somewhere (e.g. better do not use \parbox inside a caption ...), but for normal captions it seems to work. Feedback about problems is welcome!

This patch resolves the caption font issue in my test files.

However, the interaction with list of figures still occurs, leading to warnings:

Package tagpdf Warning: Destination 'figure.caption.11' has no related
(tagpdf)                structure.
(tagpdf)                /Ref not updated.

This patch does resolve the font issue of the caption for float. Thanks.

@John02139 try with this addition:

\renewcommand*\caption@anchor[1]{%
      \ifmeasuring@ \else
        \caption@raisedlink{\MakeLinkTarget*{#1}}%
      \fi}%  

[John02139]

If I do this in my cls file, the tagging warning is cured:

\AtBeginDocument{
	\renewcommand*\caption@anchor[1]{%
        \ifmeasuring@ \else
           \caption@raisedlink{\MakeLinkTarget*{#1}}%
        \fi}%  
}

(I guess I am uncertain of the correct loading order.)
