A major accessibility problem with this: the list uses <div>s with click handlers, rather than links. This makes it not respond properly to clicks with modifiers (e.g. Ctrl+click), not have the right context menu options, not show the href in the status bar, and be completely unusable to users of tools like screen readers or those that would navigate by keyboard.

Never ever do this. If it opens a new page, it’s a link. <div> with a click handler is the wrong thing >99.99% of the time: it should be a link or a button.
