Subject: [PATCH] fix: shared chat pages keep reloading and jump back to the
 bottom (#32725)

Since 0.12.3, any chat opened under /s/, whether through a share link or by an admin viewing another user's chat, was fetched again and again from the moment it opened, and each fetch scrolled the page to the bottom. Scrolling up was impossible and older messages never loaded. The chat is now loaded once when the page opens.

Fixes #32657
