fix(web): long titles no longer overflow the pull request list tooltip - #28077

Eligibility
The change lets tooltip content shrink within existing width limits so long pull-request titles can truncate properly. Its effects are confined to presentation, with no changes to product settings or data handling.

Additional Thinking

Your Custom Policy

Applied the default risk criteria. The layout repair changes no product defaults and adds no diagnostic-suppression directives, so neither additional human-review requirement applies.

Code

Adds min-w-0 to the shared tooltip viewport flex item, allowing content to shrink within existing popup width limits. This affects tooltip layout across the web app, not data, external operations, or application settings.

Review Context

The author is a repository admin and ping-devs member; no code-ownership requirements were supplied. The supplied review check reports no unresolved comments or correctness findings; no blocking severity or CI results were supplied. The PR description reports Chromium before/after verification of the actual pull-request badge with the app stylesheet.

Verdict

The shared reach is understood, and the effect is limited to tooltip content sizing under existing width constraints. No consequential product decision, persistent effect, or obvious material risk requires human judgment.
