Describe the bug
There are some instances where there will be "holes" in the list of messages. That is, a message that is hidden among a list of visible messages.

To Reproduce
Steps to reproduce the behavior: TODO: Add repro steps

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
There should be no random hidden messages.

This has been partly fixed by 1.4.2, but issue still happens sometimes.

This might be fully fixed by 1.5.0. Will re-open if someone else reports.
