onMessageUpdated not called for sender

When calling GroupChannel.updateUserMessage(), the onMessageUpdated handler is not firing on the sender’s browser.
According to Update a message | Chat JavaScript SDK | Sendbird Docs, the sender is supposed to also have the callback run.

// If problem, please fill out the below. If question, please delete.

[Reproduction Steps]

// somewhere
updateUserMessage('[a message ID]', {
      message: '',
      data: 'deleted'

// GroupChannelHandler
onMessageUpdated: (channel, message) => {
        console.log('message updated:', message); // this is not being called


[Current impact]
Need to trigger the desired logic manually in the place where updateUserMessage is called.
