hardhat is not able to figure out function selector even though they are available as part of the source artifacts

3.0.6

What happened?

I am using a proxy contract and when there are reverts the hardhat console show these :

eth_estimateGas

but these function selector should be known to hardhat as the implementation contract is one of source artifact hardhat knows about

Minimal reproduction steps

• deploy a proxy with implementation
• call it in a way that it reverts

I can confirm this is happening:

eth_call
