Code Review ✅ Approved 1 resolved / 1 findings

Clean E2E test addition for Tags page navigation. The previous finding about the fragile SVG locator has been resolved — the code now uses the proper .ant-tree-treenode / .ant-tree-switcher pattern consistent with the rest of the file. No new issues found.

✅ 1 resolved

✅ Edge Case: Fragile SVG locator for expanding Governance tree node

📄 openmetadata-ui/src/main/resources/ui/playwright/e2e/Pages/ExploreTree.spec.ts:180
The Governance node expansion uses page.locator('div').filter({ hasText: /^Governance$/ }).locator('svg').first().click() which is fragile — it depends on the exact DOM structure and could match unintended elements if the page layout changes. While this matches the existing pattern at line 105-110, both instances would benefit from a more robust selector.

Consider using a dedicated data-testid on the expand/collapse toggle, or clicking the tree node's expand icon via a more targeted selector like:

await page.getByTestId('explore-tree-title-Governance').locator('..').locator('svg').first().click();

This is a minor concern since it follows the existing codebase convention and the existing test at line 105 uses the same pattern successfully.
