main ← fix-chat-back-button-starred
merged 03:55PM - 21 May 26 UTC
When the chat drawer is closed and reopened on a starred channel, the back butto…n took the user to the default channels list instead of the starred-channels list they had originally come from.
Root cause: `chatHistory.visit(route)` always appended to history. When the drawer reopens to `lastKnownChatURL` (the channel itself), the same route is appended a second time, shifting `previousRoute` off the original `chat.starred-channels` entry. The back-button fallback in `drawer-routes/channel.gjs` then routed to `chat.channels`.
Fix: dedupe consecutive identical route visits in `chatHistory.visit` by comparing name and params (via `deepEqual`). Reopening to the same URL no longer clobbers the user's real navigation context.
Adds a unit test for the dedup behavior, a system spec covering the close/reopen scenario, and a view-agnostic `open_channel_row` helper on the drawer page object (the existing `open_channel` is scoped to the channels-list view only and doesn't work from the starred view).
