Emit doesn't work properly when using layout builder display

Problem/Motivation

I'm using a radioactivity field on a content type that's using Layout Builder → (see field settings in attached screenshot).

When the page is viewed, drupalSettings.ra_emit_0 does not exist, but drupalSettings.ra_emit_1 does exists.

In radioactivity/js/triggers.js, it is assumed that drupalSettings.ra_emit_0 will always exist before any other incremental variations. If drupalSettings.ra_emit_0 doesn't exist, like in my case, emit data doesn't get pushed into the emits array, and never gets posted via ajax.

I've confirmed that the emitter works properly when Layout Builder is turned off for the content type.
