The contents of atom-text-editor elements are no longer encapsulated
within a shadow DOM boundary. Please, stop using shadowRoot and access
the editor contents directly instead.

For people searching to fix this in their local installation, you can simply open the file in your .atom/packages/markdown-scroll-sync/lib directory and change this line:
lineEles = @editorView.shadowRoot.querySelectorAll '.lines .line[data-screen-row]'
to this:
lineEles = @editorView.getRootNode().querySelectorAll '.lines .line[data-screen-row]'

and restart Atom.
I hope this helps you out until @vincentcn finds someone who will take over this project and a new version is published.

In the latest version, according to your method, the plug-in will be invalid.

@lucasvieites @mark-hahn The latest version of the atomic editor, if it is modified in this way, this plug-in will be meaningless
