If you type something generic into the URL text field under the Navigation App Bar (like "l"), you'll notice that there will be some jank while the autocomplete search slides into view from the bottom. Some times the autocomplete search will flicker quickly.

Video of the issue:
- (doesn't really show the jank that well)

Steps to reproduce the issue: (make sure you have a good amount of history)

1) Open fxmetro
2) Once opened, type something very generic into the URL text field (I used "l")
3) You'll notice that when there's a good amount of results, the autocomplete search screen will jank while sliding into view

Current Behavior:

- autocomplete search janks when sliding into view when there's a lot of results being loaded

Expected Behavior:

- the animation should be smooth when the autocomplete search slides into view when users start typing in the URL text field.

Found the issue using the following build:
In this video, you'll be able to see that the autocomplete search window slides from the bottom and overlaps the Navigation App Bar while it transitions to the top. The animation doesn't look smooth and feels really janky
