[i18n] duplicate boolean field is not reactive

**Describe the bug**

I have a duplicate boolean field `comments`, when changing it in one locale, the field won't sync in other locales.

> The problem is that the boolean widget does not update in real-time, while string and other widgets do. Once you save the page and refresh it, it will switch to the correct value.

**To Reproduce**
Have a boolean widget with `i18n: duplicate`, show 2 locales side-by-side, and toggle it. The widget on the other locale will not update.

**Expected behavior**
The toggle on the second locale should provide feedback in real time as the string widget does.
