Previously, the "Jump to..." button in the "Change reply target" modal did nothi…ng and leaked out of the modal, along with the notifications bell ([meta](https://meta.discourse.org/t/415128)). Investigating it surfaced related timeline bugs, several features broken on mega topics (10k+ posts), a site setting that could be replaced by CSS, and a composer render race. This change fixes them in separate commits: - **FIX: Hide timeline footer controls in the reply target picker.** The modal's hide rule lost to a more specific core rule. - **FIX: Typos and dead code in the topic timeline.** `fullScreen` typo, a guard that never matched, and a docked back button that has been invisible and unclickable since 2023. - **FIX: Features relying on the post stream in mega topics.** Mega topics get no `stream`, so last read markers, back buttons, "Quote post", "Edit first post", "New topic" from share, jumps to unloaded posts, the topic map's user count and the post voting header were broken. - **UX: Replace `short_progress_text_threshold` with automatic fitting.** CSS now hides "/ total" only when it doesn't fit; the setting is removed. - **FIX: Load the composer category before rendering.** With lazy loaded categories, the composer rendered before its category loaded, logging warnings and a `DTextField` render error. ### Screenshots | | Before | After | |---|---|---| | Reply target picker | <img src="https://github.com/user-attachments/assets/8b548486-f84c-41e6-91ae-1aaba7724783" width="400"> | <img src="https://github.com/user-attachments/assets/8ea15fe0-4cb9-4d60-9176-92fb21f7e560" width="400"> | | Picker on a mega topic | <img src="https://github.com/user-attachments/assets/73e1132e-9974-403c-9508-d4c324227e11" width="400"> | <img src="https://github.com/user-attachments/assets/953156f7-e7bd-4e3b-940c-acbb47dd8b09" width="400"> | | Timeline on a mega topic | <img src="https://github.com/user-attachments/assets/0e58dd54-3e1c-4357-a9f9-369df2c91fb4" width="120"> | <img src="https://github.com/user-attachments/assets/6dff991c-1f66-44af-a068-9316a2a2571c" width="120"> | | Topic map on a mega topic | <img src="https://github.com/user-attachments/assets/0a8d1af3-623d-4c92-9927-8922574b21a3" width="400"> | <img src="https://github.com/user-attachments/assets/0713d0a7-129c-4059-8657-0e7ab9268f44" width="400"> | | Mobile progress bar on a mega topic | <img src="https://github.com/user-attachments/assets/83891919-bc84-47f4-88c2-bd6a1ed037a6" width="300"> | <img src="https://github.com/user-attachments/assets/d8603313-1dc2-46fc-a6b8-abe80038336a" width="300"> |
