Sidebar navigation should expand subfolders & show selected doc when linked externally#584

If a wiki doc is linked to me, it opens the doc on the right, and I can see the list of folders on the left, but it’s not immediately clear which folder/subfolder the doc that’s open on the right is in.

I’ve regularly had to open a lot of folders and subfolders before finally finding where the doc I’m looking at is stored.

Would be a lot more convenient if the left nav automatically jumped down to and expanded the folder/subfolder related to my doc and put it immediately within view.
