Note: We do not have exact data for 2c43e0fd. So we have used data from: 2f6a983d.
The target commit was too new, so we used the latest commit from master we have info on.
It might help to rerun the bundle-size-review job
This might mean that you have a few false positives in this report. If something unrelated to your code changes is reported, you can check this comparison in order to see if they caused this change.
