Especially for the first time after browser start there is noticeable delay in autocomplete popup display that I don't remember to be present in the previous version.

The first query in a session will always be slower cause there's a bunch of caches to populate.
I think currently it looks slower cause it's an async query, while before it was a synchronous query. Being synchronous it was blocking the UI (causing jank) but on the other side it was getting the maximum priority from the OS.
While we'll keep looking into perf improvements to reduce the problem, I don't think we can completely revert the behavior, since we don't want to block the main-thread.
I'm marking as a wontfix cause it's not directly actionable, but expect us to do more work on the perf side.
