Applied as-is. A tab that is still choosing a reconnect token now answers another tab's query for the same candidate hashes, so a tab started during the 150 ms window cannot adopt a token the earlier tab is also considering. The smaller tab id still wins, and a tab that already holds the token keeps it.
Tests: node --test test/client-identity-session.test.js test/client-static.test.js — 319 pass, 0 fail.
