Fix/locale selector

[vitorflg]

What problem is this solving?

The context for this change is in the #prod-muji-eu channel.

1. On a binding selector change, the block selector not works without toggling it.
2. On a locale selector change, the block selector not works until the page is reloaded.

How should this be manually tested?
