Chai lengthOf matcher not compatible with ethers/waffle objects

[ItsNickBarry]

let quorum = ethers.constants.One;
let signers = await ethers.getSigners();

expect(quorum).to.be.at.least(1);

expect(signers.length).to.be.at.least(quorum);
expect(signers).to.have.lengthOf.at.least(1);
expect([1]).to.have.lengthOf.at.least(quorum);
expect(signers).to.have.lengthOf.at.least(quorum);

All statements run successfully except for the last one.

The error message is not particularly helpful: AssertionError: Expected "[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]" to be at least 1

Previously reported to Hardhat.

Thanks for reporting @ItsNickBarry. Until there's fix for this, you can cast expected length to normal number
expect(signers).to.have.lengthOf.at.least(quorum.toNumber())
