fix(webview): render expanded task header text as markdown with consistent scrollbar - #1257
Conversation
The collapsed task title still shows raw text, but the expanded view rendered the prompt verbatim via <Mention>, so markdown syntax (bold, code, lists) appeared as literal characters. Render it through MarkdownBlock like other chat messages and drop the now-redundant whitespace-pre-wrap class.
The expanded prompt box used a default always-visible Chromium scrollbar while the message list uses the hover-reveal .scrollable style, so two differently-styled scrollbars stacked in the same column. Add the shared .scrollable class so both behave consistently.

…wn links MarkdownBlock renders prompt links as <a> elements, which the header click handler did not guard against (only buttons/role=button/img), so clicking a link inside the expanded prompt toggled isTaskExpanded and collapsed the panel. Ignore anchor targets in the toggle handler; add regression tests for link clicks, headings/lists rendering, and empty prompts.

ClineMessage.text is optional (z.string().optional()), so the empty-prompt case can omit the property instead of casting undefined through any.

This removes the existing openMention click behavior for context tokens such as @/src/file.ts, @problems, and @terminal whenever the header is expanded. Can we preserve context-mention rendering in the markdown path and add an expanded-mention interaction test?
