🖊 A gtk3 markdown editor

---

Preamble (About this Fork)

This fork contains a workaround for issue#191: Preview scrolls to the top when changing the document.

Cause of the Problem

• webkit_dom_element_get_scroll_top returns zero even when the view's scroll state is definitely non-zero.
• WebKit deprecated this and other functions since version 2.22 (with a hint to use the JavaScriptCore API instead). Affected are webkit_dom - functions. They are used in the scroll-extension. It still compiles & links but with warnings.

How it is fixed

• Implemented scroll capturing and restoration directly in marker-preview running JavaScript snippets.
• Disabled scroll-extension.

Current Status

• Meanwhile the issue has been fixed in the original repository by a different and probably better approach. I'm keeping this workaround for my own reference (and for those who might be interested :-) ).
