Is there a maximum size of a scriptSig/scriptPubKey?

Is there a maximum size of a scriptSig/scriptPubKey?

Previous research:

Are there any consensus rules that prohibit scripts from being too large? I know each individual element of a script has to be less than 520 bytes, as shown here, but a script could still have many many individual elements and create an extremely large block.

For example, a malicious miner wants to make the blockchain as big as possible and creates a coinbase transaction with a particular output that has the OP_RETURN opcode followed by enough data to make their block just less than the 1 MB limit. Will the malicious miner's block, in which 99% of the block data is encoded into a dummy OP_RETURN output, be accepted or rejected?
