/// A data source which cannot be used stays in the list instead of disappearing from it, but cannot
/// be picked, and the tooltip says why. The tool selection next to it in the chat answers the same
/// question the same way.
///
/// Why it cannot be used decides what the row says and which icon it wears: an index being built
/// anew is a matter of waiting, an index which cannot be read is a matter of acting. Both are the
/// same row otherwise, which is why this is one component with a reason rather than two components.
///
/// The tooltip sits around the list item rather than inside it: a disabled item has its pointer
/// events switched off and would swallow the hover.
