Clicking On Bookmarks Folder in Private Window New Tab Crashes App

1. Open Private Window
2. Open new tab
3. Click on a bookmarks folder within the favourites list

For some folders, the browser crashes completely. For others, an arrow appears at the top as if the folder had opened, but the folder does not actually open (i.e. nothing else changes visually). I'm not sure what the pattern is for which of these cases occurs, but it is consistent between launches.

Clicking on bookmarks folders within Private Window new tab should behave the same as in normal windows.
