@danielleroux The fix is done and the visual regression test is done. Its not passing the build only here, on my machine works perfect. I think its because it is expecting to have a snapshot from a linux, you should just run the tests, and commit the snapshot.

Did you executed the test inside Docker?

I will update the snapshots.

@goncalosard I checked the PR i will refactor the changes regarding the breadcrumb a little bit, because it is more sustainable to adapt the max-height within the dropdown it self
