Navigation bar appears at the wrong height when switching back to Eateries tab

Recreate:
1. Open eateries page and open an eatery
2. Open lookahead tab
3. Go back to eateries page
4. Use the left-swipe gesture to go back to the Eateries page
5. The navigation bar is now too high up, but this fixes itself when you scroll or do anything

Reproduce the navigation sequence in the issue: open an eatery, switch to Lookahead, return to Eateries, then use the left-swipe gesture. Trace the Eateries and Lookahead navigation transitions and navigation-bar layout; done means the bar remains at the correct height immediately after the gesture without requiring scrolling.
