Description text in the GTK4 and libadwaita pages are not parsed correctly

[ryonakano]

Describe the bug
Pictures, code blocks, links, etc… some syntax in the description text GTK4 and libadwaita pages are not parsed correctly.

To Reproduce
Steps to reproduce the behavior:

1. Open some original C version of the documentation page, e.g. Adw.ApplicationWindow. See there are some links to other pages and the screenshot of the Adw.ApplicationWindow is shown in the Description section.
2. Open the coordinate page in Valadoc: https://valadoc.org/libadwaita-1/Adw.ApplicationWindow.html
3. See the links and screenshot is not parsed in the Description section; they're shown just like the normal text.

Expected behavior
Links and pictures in the Description page should be parsed correctly as the original documentation.

Screenshots
Here is the original C version (and expected behavior):

This is the current result of Valadoc:

Desktop (please complete the following information):

• OS: Fedora Rawhide
