Hello!
I use your script for my Slack app on Ubuntu 16. It worked fine until I updated my packages. I guess the Slack package must have been updated and it stopped rendering math. I rerun your script as mentioned in the doc and restarted slack, but then the slack window was completely blank.
I uninstalled and reinstalled the Slack app, which displayed correctly again. Then I ran your script again and started Slack, but still got a blank window.
I have this version of Slack: 2.6.0 64-bit Beta Channel
