Describe the bug

A user asked on stackexchange why their anchor IDL doesn't show up on our Explorer: https://solana.stackexchange.com/questions/9569/idls-explorers-curiosity

Explorer link to their program: https://explorer.solana.com/address/propm845StqEBV57ZSnTe8EW8duzAxo5p7h4inhibXV?cluster=devnet

I took a look at Explorer and I think the code that fetches the IDL is this:

explorer/app/providers/anchor.tsx

Lines 10 to 37 in 5dcb646

    
           export function useAnchorProgram(programAddress: string, url: string): Program | null { 
        
               const key = `${programAddress}-${url}`; 
        
               const cacheEntry = cachedAnchorProgramPromises[key]; 
        
               if (cacheEntry === undefined) { 
        
                   const promise = Program.at( 
        
                       programAddress, 
        
                       new Provider(new Connection(url), new NodeWallet(Keypair.generate()), {}) 
        
                   ) 
        
                       .then(program => { 
        
                           cachedAnchorProgramPromises[key] = { 
        
                               __type: 'result', 
        
                               result: program, 
        
                           }; 
        
                       }) 
        
                       .catch(_ => { 
        
                           cachedAnchorProgramPromises[key] = { __type: 'result', result: null }; 
        
                       }); 
        
                   cachedAnchorProgramPromises[key] = { 
        
                       __type: 'promise', 
        
                       promise, 
        
                   }; 
        
                   throw promise; 
        
               } else if (cacheEntry.__type === 'promise') { 
        
                   throw cacheEntry.promise; 
        
               } 
        
               return cacheEntry.result; 
        
           }
