When a chat is started from the home page, the URL is switched to /c/{id} with
history.replaceState, so the Chat component is never remounted and chatIdProp
stays empty for the lifetime of that view. Both websocket recovery paths,
handleSocketConnect and the chat:active fallback, are gated on chatIdProp and
therefore never run for these chats. After any websocket drop during a response
(mobile backgrounding, VPN or IP change, wake from sleep) the completed response
is never fetched and the chat stays stuck in a loading state until a manual page
refresh. Chats opened directly via /c/{id} recover fine, which is why the bug
only reproduces reliably on freshly started chats.
Gate both recovery paths on the chatId store instead, which is set for every
persisted chat, and let loadChat fall back to it so the recovery reload also
works when chatIdProp is empty. Chats opened via /c/{id} behave exactly as
before and temporary chats stay excluded.
The same gate likely explains the remaining reports in #26315.
Fixes#26844
The system-terminal HTML file preview (FilePreview.svelte, serveUrl branch) rendered served HTML in an iframe that hardcoded allow-same-origin. The terminal proxy serves the file root-relative (same origin as the app) and injects no CSP, and there is no default global CSP, so script in a previewed HTML file executed in the application's own origin and could read localStorage (the session token), enabling account takeover and, for admin or workspace.functions victims, server-side RCE via Functions. The sibling srcdoc branch already gates allow-same-origin behind the iframeSandboxAllowSameOrigin setting (off by default) and injects a CSP; the serveUrl branch never received that defense. Gate allow-same-origin on the serveUrl branch identically, so by default the preview runs at an opaque origin and its scripts cannot reach the parent context. Legitimate HTML preview rendering is unaffected.

- Move setModels() and setToolServers() out of the loaded gate in
+layout.svelte so the page renders immediately instead of blocking
behind slow/unreachable connection timeouts
- Track failed Ollama backend URLs from /api/tags and skip them in the
subsequent /api/ps fan-out, eliminating a redundant second timeout
- Silence the autocomplete toast that fires during the transient empty
model state
Add a custom MIME type (application/x-open-webui-drag) to intentional
chat and folder drag sources. The onDragOver handler in MessageInput
now checks for this type instead of the generic text/plain, which
SortableJS also sets during reorder operations for pinned menu items
(Notes, Workspace) and pinned Models.
