Description
Re https://forums.ankiweb.net/t/default-browser-search-to-current-card-note-only/17863/9
With multiple hundreds of thousands of cards nested under one primary deck, the search query can take 500ms+ on a fast machine, especially if the sort field column is selected. This compares to about 50ms for no explicit sorting, and about 5ms for a deck with only a few cards.
Previous Anki versions showed only the current card on startup, to avoid this delay in opening. We might want to think about bringing that back, or finding some other way of improving opening time.

Research direction
No files, tests, or entry points are named. Reproduce browser startup with a deck containing hundreds of thousands of cards, compare sorted and unsorted searches, and determine whether restoring current-card-only startup or another approach meets the opening-time goal.
