Summarise A Messy Bug Report Thread Into A Clear Ticket

A bug got reported in a thread that spiralled into forty replies, half of them someone asking if anyone else can reproduce it. This pulls out the actual symptom, the reproduction steps, and the environment details, then flags any contradiction still unresolved. For anyone who triages tickets and is tired of reading the whole thread every time.

<context>
A long back-and-forth thread reported a bug: {BUG_THREAD}. It contains repeated questions, half-answers, and at least one contradiction about when the issue started.

<task>

1. State the actual symptom in one sentence, as experienced by the user
2. State steps to reproduce, inferred from the thread, flagging any gap
3. Note environment details mentioned (browser, version, device) if present
4. Flag any contradiction in the thread that needs resolving before work starts
