Monticello figure (`SBE-apb.png`) fails sporadically

[LinqLover]

Sometimes the Accept button is not found. Since I could not reproduce the issue locally, I placed an ugly debugging hack in the figure script (https://github.com/hpi-swa-lab/SqueakByExample-english/pull/119/commits/6faf70044b77e3cbec11d684f586e4d1c10d0996) that will allow us to understand the issue as it occurs again.

Maybe we would just need to increase the <timeout: ...> for this series. However, without any flake metric for the tests (could be retrieved from the CI logs using the GitHub API), this feels like a shot in the dark.
