Steps to reproduce: 1. Open Preferences. Select "Use Bookmark...", do nothing else here. 2. Open a new tab. Pretend you did something in it, though nothing is required. 2. Press Cmd-, or go to Nightly -> Preferences... again. Expected result: I'm returned to the Preferences tab. Actual result: I'm returned to the Preferences tab, my in-progress Bookmark selection is cleared, and the entire tab reloads, flickering the tab title briefly to about:preferences and then back to Preferences.

This is by-design. It's entirely possible the next loading of Preferences needs to take the user to another section or pane, even if we probe the currently loaded section/pane we cannot prevent reloading/switching in that case.
