SUMMARY
Some markdown in headings resets font size to normal text.

STEPS TO REPRODUCE
1.  Define a title like this: "# Normal `mono` **bold**" normal

OBSERVED RESULT
The word "Normal" uses the expected font size. Any subsequent word is rendered with normal text font size, despite being part of a heading.

EXPECTED RESULT
All text within the heading uses the same font size for that heading level.

Comment 2 Friedrich W. H. Kossebau 2024-10-28 12:18:45 UTC

Thanks for the report.  The markdownpart itself though does not do any related processing, instead completely relies on Qt's QTextDocument::setMarkdown() method to do the formatting.  See also MarkdownPart::openFile() implementation at
https://invent.kde.org/utilities/markdownpart/-/blob/master/src/markdownpart.cpp?ref_type=heads#L112

So this bug report needs to be filed upstream against Qt, please.

Why the status is "RESOLVED UPSTREAM"? Is has not been solved at all yet!

That is an unlucky display of the status, there should be a "," in the middle. The status relative to the product here is "resolved", with an indication this is an "upstream" issue.
