… `findDefinition` method (sroze) This PR was merged into the 3.3 branch. Discussion ---------- [DependencyInjection] Prevent a loop in aliases within the `findDefinition` method | Q | A | ------------- | --- | Branch? | 3.3 | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | #25338 | License | MIT | Doc PR | ø This prevents an infinite loop going when aliases reference themselves. This is based on 3.3 as the "normalized ID" changed to allow non-lowercase names. Fixing this in 2.7 would mean a merge conflict that IMO is not worth it.
