[Bug] Cannot select/copy text in some web UI elements

Description

Description
In the OpenCode web interface (opened via opencode web at http://127.0.0.1:4096/), I cannot select and copy text in certain response elements. The text simply won't highlight with the mouse — this looks like user-select: none in the CSS.

The problematic elements (found via DevTools):

Assistant answer block:

Tool subtitle:
Regular text elsewhere in the UI selects and copies fine.

Expected behavior
Any text in responses should be selectable and copyable with the mouse (Ctrl+C).

Actual behavior
In the elements above, the text cannot be selected or copied.

Environment
OpenCode Web (opencode web)
URL: 127.0.0.1:4096

Browser: Chrome / Firefox (specify)
Note
This may be the same class of issue as the previously fixed case for question-option (user-select: none), see PR #39868. It appears user-select: none is also applied to answer-text and basic-tool-tool-subtitle.
