## Summary
Fixes flaky screenshot test that was identified during the PR #9400
snapshot update, where baselines regenerated without any code changes
affecting them.
**Root cause:** `fillAndSelectFirstNode('KSampler')` selected `nth(0)`
from the autocomplete dropdown, but search result ordering is
non-deterministic when the search box opens via link release with filter
chips. Sometimes 'Preview Image' appeared as the first result instead of
'KSampler', causing a completely different node to be added.
**Fix:** Added an `exact: true` option to `fillAndSelectFirstNode` that
uses an `aria-label` selector to click the specific matching result
instead of blindly selecting the first item.
- Fixes#4658
