Chat view is not always scrolled to show last message

We use the bundled Mattermost 1.3.0 build 4977 instance on GitLab 8.3.2 (running in a Docker container).
Using Chrome 49.0.2623.28 beta (also tried stable), the chat view does not always scroll to the bottom when I send a message, so my last message is often hidden, until I manually scroll down.
Anyone else see this phenomenon?

There was an issue with this previously, but it looks like it should have been fixed in v1.3.0. I haven’t seen it since then, would be interested to hear if anyone else has seen it on recent versions.
