Sync does not affect search engine customizations

Description of the issue:

I bothered to customize the search shortcuts on one browser, but I am not seeing changes reflected on other browsers. That is a lot of work to set up properly, so I would expect them to sync when you have Settings selected for sync. Other aspects of Brave Sync are working properly

Steps to Reproduce (add as many as necessary): 1. 2. 3.
Set up sync chain. Customize search engines. Check another computer on sync chain.

Reproduces how often:
Always

Brave Version(See the About Brave page in the main menu):
Version 1.23.73 Chromium: 90.0.4430.85 (Official Build) (64-bit)

Type of devices currently running on the Sync chain in question:
Linux, Windows, iPhone, iPad
