Allow disabling "Show Browser suggestions" while being able to keep "Show search suggestions" enabled

[Lyti4n]

Description

Right now disabling "show browser suggestions" locks you out of being able to enable "show search suggestions". This isn't how it works on desktop, and is quite annoying. For me personally I would like to be able to have suggestions from my search engine show up as I'm typing without having all of my bookmarks and previous history show up too.

Steps to reproduce

1. Disable "Show browser suggestions"
2. "Show search suggestions" no longer appears

Actual result

You can't enable them independently

Expected result

You should be able to enable them independently
