📝 Description
This PR addresses an issue where users attempting to join a nomination pool via the UI were not able to contribute tokens locked in OpenGov. While the UI allowed joining the pool, it incorrectly excluded tokens locked for governance participation. The same action can be performed successfully through the Extrinsics page, which clearly indicates a bug in how the UI calculates eligible token amounts.
On Polkadot and its parachains, governance-locked tokens can be used in other staking-related operations. The issue was specific to how balances were computed or filtered on the client side when constructing the join pool extrinsic.
✅ Fixes
🤔 Previous behaviour
Here is the account details used for testing, which have 40 PAS locked in OpenGov.
