This seems to still sort of exist, so now clicking actually opens and if you are in preview it opens nicely with no issues.
However if you are in EDIT mode and you CMD+SHIFT+CLICK it does open the note in a new pane BUT the original note will have text highlighted up until that link, seems minor but would be nice that it does not do any highlighting as it adds an extra step to un select. Minor.
Edit: Rolled into a new report here CMD/CTRL+SHIFT CLICK Links highlights text in edit mode and this topic should be closed as solved.
