easterbrooka patches the chat surface where assistant replies render

The fork owner pushed through a fix to the part of the chat interface that turns an assistant's response into the HTML you actually see on screen - and to how nested messages (replies, quoted context, sub-turns from tools or agents) sit inside that outer message. The branch name is the only public signal: no description, no review, merged nine seconds after opening.

Problems in this area usually look like missing formatting, broken nesting, or content that quietly disappears because a sanitiser stripped it. The fact that both the outer body and the inner messages were touched in one go suggests a shared root cause in the rendering path. The speed of the merge reads like a maintainer clearing a visible UI bug rather than shipping a feature.
