Take a look at https://github.com/code-423n4/2024-03-zksync/blob/4f0ba34f34a864c354c7e8c47643ed8f4a250e13/code/contracts/ethereum/contracts/state-transition/chain-deps/facets/Getters.sol#L162-L174
This function is used to determine if a facet is freezable, issue here is that it wrongly uses if() instead of require() now since if is used, in the case where the facet is none existent selectorsArrayLen == 0 would be true and as such the function would return false whereas it should revert since the facet is non-existent
Users would be confused at this, since there is no difference between unfreezable facets and non-existent ones considering the current implementation of isFacetFreezable().
Consider changing the if() condition to require() that way only real unfreezable facets would return false.
