This problem was fixed in Delphi 13.2.
So, if you upgrade from Delphi 13.1 to 13.2, this workaround is no longer needed.

1. This fix was included in the TRichView update
2. RAD Studio 13.2 fixed the problem with copying TSkGraphic and TSkSvgGraphic to the clipboard: no exceptions anymore; nothing is copied. But TRichView implements copying them as bitmaps.

If you use ReportBuilder 22.x, open <TRichView>\ThirdParty\ReportBuilder\Source\Include\RVRB.inc, and remove the line This line is necessary for ReportBuilder 23 and newer.

Does it help?

Without StyleTemplates, Markdown will be loaded using default character attributes.
For example, *text* will be loaded as an italic text, instead of using properties of 'Emphasis' StyleTemplate.

Can you double check that this manifest is really used and is not overridden by some other manifest?
