The search engines dropdown menu doesn't display newly-added search engines properly

[Tonev]

Description

Users can't choose a newly-added search engine from the dropdown menu at brave://settings/search unless the newly-added search engine is selected as default at brave://settings/searchEngines.

If users choose another search engine from the dropdown menu later, their previous search engine (the newly-added search engine from my previous sentence) will disappear from the dropdown menu, and users will have to make it default if they want to be able to choose it from the dropdown menu once again.

Steps to Reproduce

1. Add a search engine at brave://settings/searchEngines
2. Check the search engines dropdown menu at brave://settings/search
3. The newly-added search engine won't appear unless you make it default at brave://settings/searchEngines

Actual result:

Q8yHiuF6Id.mp4

Expected result:

Users should be able to select newly-added search engines from the dropdown menu without having to make those search engines their default.

Closing as wontfix. This is working as expected as the list in that the drop down are the default search engines that ship with the browser. The number of search engines available via the drop down list could be exceptionally long if we add all the opensearch engines in there.

Not that my comment will change anything, but I'll reply anyway.

The number of search engines available via the drop down list could be exceptionally long if we add all the opensearch engines in there.

If only the predefined default search engines + manually-added search engines are displayed in the dropdown menu, the list won't become exceptionally long. Right now, you're limiting Brave users to seeing only the search engines the developers have selected as default for one reason or another. There is absolutely no need to display every search engine that Brave adds at brave://settings/searchEngines, or in other words: https://community.brave.com/t/how-does-other-search-engines-added/261224.

What you're describing as "working as expected" might be true, but at the same time the feature is limiting users only to Brave's predefined "default" search engines, which could be changed for better.

Best regards.

Is this still a wontfix if brave/brave-core#9602 is the first step in implementing what I suggested?
