Rails 7 `turbo_stream_from` not updating view

Question

Running Rails 7.0.4 and trying to get a basic turbo_stream_from implemented. According to logs, it's broadcasting/transmitting appropriately, but the view itself is not updating.

My issue appears to be identical to this question, but the solution with Redis not being running/installed is not my issue (Redis is properly installed and running).

Have restarted the app, console and redis a dozen times.

# show.html.erb
<%= turbo_stream_from "documents" %>

# document.rb
class Document < ApplicationRecord
  after_update_commit -> { broadcast_update_to "documents", partial: "documents/summary", locals: { document: self }, target: "document_#{self.id}" }
end

# documents/_summary.html.erb
<p class="mb-3 text-sm text-slate-500"><%= pluralize(time_to_read(document.summary), "minute") %> &bull; <%= word_count(document.summary) %> words</p>
<%= markdown document.summary %>

This is what I see on the rendered page:
