Markdown tables unreadable in dark mode

I've updated to the beta version (1.4 release 5937). Now the preview looks better, as it consistently uses light mode even if the OS is switched to dark mode.

However the email recipient still sees white text on a white background for tables and code blocks. I guess it is hard or even impossible to generate HTML that honors the light/dark theme for the OS, since for the generated HTML all CSS rules must be moved into style attributes of the HTML elements. However a style attribute doesn't support media queries. So we might have to stick to one theme for the email. However the problem with the HTML as it is currently generated is the following. The HTML generated for code blocks looks like this:

<pre style="margin-left: 15px; margin-right: 15px; padding: 5px; background-color: #F7F7F7; border-radius: 5px 5px 5px 5px; overflow-x: auto; max-width: 90vw;">
   <code style="margin: 0 0; border-radius: 3px; background-color: #F7F7F7; padding: 0px;">
      &lt;?ul4 la_table_headrow(app, content=None, id=None, cssclass=None, cssstyle=None, hide={/})?&gt;
      &lt;?whitespace strip?&gt;

I.e. it specifies a background color, but no text color, so the email client chooses a text color that best matches the OS color theme, which in dark mode is white, which gives us white text on a nearly white background.

Of course the background color for pre and code could simply be removed so that the email client can choose an appropriate background color too, but this will fall as soon as the code block uses syntax highlighting. So the better option might be to set the text color too.

Does anyone still have this issue? I'm unable to reproduce it (the white text).
