[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.

Additional context

I don't see a comments field in your config, could that be the problem?

[razonyang]

Sorry, I cut off the wrong part, updated with full configuration (maybe too long).

[martinjagodic]

What happens if you remove default and/or required? nav_weight doesn't have them, does it work as expected?

[razonyang]

What happens if you remove default and/or required?

Same issue when 1) remove one of them, 2) remove all of them.

nav_weight doesn't have them, does it work as expected?

Yep, the nav_weight works as expected.

[razonyang]

The field will be synchronized after clicking the Toggle i18n button twice.

Could you prepare a minimum reproducible config? This one is very large so it's hard to determine the real culprit

[razonyang]

Sure.

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.

I have other priorities at the moment but I would gladly accept a PR that fixes this.

I updated the original post and title to describe the issue better.
