Copy button on code blocks in web UI does not copy to clipboard (V2 UI)

Bug

When viewing a response in the OpenCode web UI, clicking the "copy" button on a code block does nothing — the code is not copied to the clipboard.

Clicking the copy button copies the code block contents to the system clipboard.

Manually selecting the text and using the browser's native copy (Ctrl+C / Cmd+C) works. But it's very clunky and irritating.

This issue might be a duplicate of an existing issue. Please check:

Copy to clipboard button for code blocks in doesn't work when opened in localhost web #32664: Copy to clipboard button for code blocks not working in the web UI (localhost) — describes the same symptom of the copy button on code blocks not working in the web view, while the full-response copy button works fine.

If your issue is the same, please add a reaction or comment on #32664 instead so we can consolidate the reports.
