Greptile Summary

Fixes the vertical alignment of » breadcrumb separators in two DevTools views (OwnersStack and SuspenseBreadcrumbs) by adding align-items: baseline to their flex containers. This ensures separator characters align with the text baseline of adjacent breadcrumb items rather than being slightly offset.

• Adds align-items: baseline to .OwnerStackFlatListContainer in OwnersStack.css
• Adds align-items: baseline to .SuspenseBreadcrumbsList in SuspenseBreadcrumbs.css
• No functional or logical issues found; both changes are minimal and correct CSS adjustments

Confidence Score: 5/5

• This PR is safe to merge — it adds a single CSS property to two files with no risk of breakage.
• The change is a minimal, well-scoped CSS-only fix that adds align-items: baseline to two flex containers. Both usages are correct and achieve the intended visual alignment improvement. No functional code is modified, and there is no risk of regression.
• No files require special attention.
