[InfectedIsm]

Hello,

Here's the project where the issue is showing: https://github.com/whetstoneresearch/doppler/tree/main/
The following files all shows the same issue as described in the title.

Files where its not working:

• src/Airlock.sol
• src/Doppler.sol
• src/UniswapV2Migrator.sol

Would be interesting to know if you're reproducing the issue on your end.

Regards
