What went wrong?

Use this public repo to replicate the issue: https://github.com/engn33r/ape-gas-anomalies

Unexpected gas report results:

1. if_greater1() has the same logic as if_greater2() but the gas report results are different
2. The gas report for uninitialize() shows 4084 gas with a default_provider of foundry but only 304 gas with a default_provider of hardhat.

The result for scenarios 1 and 2 should be that there is no difference in gas report results.

How can it be fixed?

Is this an issue with the plugins or code external to ape?
