Cannot vote with custom account permissions

[LiorHalfon]

Hi,
I've created a voting authority by doing:
cleos set account permission ACCOUNT_NAME voting '{"threshold":1,"keys":[{"key":"PUBLIC_KEY","weight":1}]}' "active" -p ACCOUNT_NAME@active
And linked it to voteproducer action by doing:
cleos set action permission ACCOUNT_NAME eosio.system voteproducer voting -p ACCOUNT_NAME@active

The reason I did this is to enable me to use the voting portal without sharing my private key with Scatter.

Now after I've set up Scatter identity ACCOUNT_NAME@voting, and paired with the voting portal, I'm getting this error:

Voting failed: Missing required accounts, repull the identity

When I change my voting identity to ACCOUNT_NAME@active in Scatter, The portal takes me to the Scatter confirmation page but then fails to authenticate the transaction. (As it should, because I don't have the ACCOUNT_NAME@active private key in Scatter)

Looks like this is an issue ( or rather a lack of functionality ) with eosjs.

This is the code that votes for producers, which just takes an account name and infers the permissions via eosjs.
https://github.com/EOSPortal/eosportal-front/blob/master/src/utils/eos.util.ts#L112

That code could be extended to provide support for custom authorities by passing it along with the account to the method and building the authorization array manually.
