Unable to import an exported `OpenSSL::PKey::EC` key

[postmodern]

I cannot seem to be able to import an exported PEM encoded OpenSSL::PKey::EC key.

Steps To Reproduce

ec = OpenSSL::PKey::EC.new('prime256v1')
ec.generate_key
pem = ec.to_pem
# => "-----BEGIN EC PRIVATE KEY-----\nMCUCAQEEID5wHE2lScjVvIkAcVXJWw5al+Jl8k7OiS+t8zAB1pOE\n-----END EC PRIVATE KEY-----\n"

ec2 = OpenSSL::PKey::EC.new(pem)

Expected Result

#<OpenSSL::PKey::EC:...>

Actual Result
