Joshua Fernandesrequested to merge
issue/ai_context-3586302:3586302-clean-up-ccc-tooltip-truncation-and-icon-only-content into 1.0.x

Description

Closes #3586302

Testing Instructions

Create one item with a long label/description and a purpose, mark it Global or scoped, and add 3+ scope values (to trigger the +N pill). Add a child subcontext (one Required, one Conditional).

1. Items list — /admin/config/ai/context/items

  • Tab through the page; with a screen reader on (VoiceOver):
  • Mouse hover still shows the tooltips.
  • Inspect DOM: decorative SVGs have aria-hidden="true" + focusable="false".

2. Agents form — /admin/config/ai/context/agents (agents with long descriptions)

  • A truncated agent description: SR reads the full description; visible text stays truncated with …. Inspect: <span aria-hidden="true">…truncated…</span><span class="visually-hidden">…full…</span>.

3. Truncated target-entity links (item referencing an entity with a long title)

  • SR announces the full entity title; visible link text stays truncated. Non-truncated labels render plainly (no redundant markup).
