Working as designed with the x button for closing the search. So I'm not sure there's a need for cancel and delete buttons for search whereas I see the need for selection.

Yeah, this is actually how Chrome works. You can't search history after selecting an item in history (in Gmail, can you still use the search function if something is selected, but searching mail will get rid of your selection and instead show the search results).
In our case, it looks funky because we have other stuff in the top nav that Chrome doesn't have, which also gets hidden if the user is engaging in searching history.

I propose leaving as is for now, but to make it less confusing in the future we might want to take the page-specific search icon out of the top nav - it seems that some people don't realize it's searching only the page and not ALL the content through Settings/Brave Rewards/History/Bookmarks/Downloads/Crypto Wallets. Also, some pages like Crypto Wallets don't require a page-search function.

Dropping the search function down to the page level might look something like this:

Of course, we'll have to think of the UI treatment for each the pages (Settings/Brave Rewards/History/Bookmarks/Downloads/Crypto Wallets) if we go in this direction.
