[josiah-keller]

Test plan

1. Ensure all suggestions switch is enabled in the search setting page
2. Have sufficient history so that suggestion are shown based on all the options
3. Try using UP arrow key to select the bottom most suggestion list, it works now

Description

Fix #7682

• Submitted a ticket for my issue if one did not already exist.
• Used Github auto-closing keywords in the commit message.
• Added/updated tests for this change (for new code or code which already has tests).
• Ran git rebase -i to squash commits (if needed).

@josiah-keller could you add some steps for testing? You can edit your original post above and then we can copy into the issue

edit: I created some steps which might be good- take a peek, let me know 😄
