Upgrade StorageLeft and right sidebar loading errors
After restarting Zotero 8 and opening the reading view, the right-hand sidebar is closed by default; whenever you switch the tab of the document you are currently reading, the left-hand sidebar (Outline) opens by default.

The state (open/collapsed) of the left sidebar is shared within the same type of tabs (e.g., readers), and the right pane state is shared among all non-library tabs.
