My plan to fix that bug is to skip environment reload if we detect the functionAppDirectory is the same during workerInit and functionEnvironmentReload. However, I want to validate a few assumptions first:
The bug itself is rare, and IMO it would be a big deal if we skip environment reload for apps that still needed it - so that's why I'd rather be careful and add logs before actually making the change.
