Symbols Sidebar not collapsing

One of my extension users reported an issue with the Symbols sidebar. Specifically, when it is in the Hierarchy view, dragging the slider to the right will expand the symbols, but dragging it back to the left does not collapse symbols back down. The same thing happens with a TypeScript file, so I assume this is a Nova (10) issue.

Thank you for the report. This has already been resolved with Nova 11.
