A user, jomaxro, reported an issue with creating polls on the Try Discourse platform. The poll would appear broken, despite using valid syntax. techAPJ suggested the issue might be related to the approval queue, as they were able to create a working poll on Try. However, jomaxro questioned whether it was indeed an approval issue. codinghorror initially considered it a low-priority issue if related to approval, but later noted that Meta and Try run the same code, suggesting another cause. jomaxro remained concerned about the root cause. tgxworld was able to reproduce the issue locally and confirmed that polls in the approval queue can become permanently broken. A pull request has been created to address the issue (https://github.com/discourse/discourse/pull/4675).
So I was looking to play around with CSS on polls, but creating a poll on Try resulted in a broken poll:
https://try.discourse.org/t/testing-poll-css/600
Here is what I attempted to enter (note that it works OK here on Meta):
[poll type=multiple min=1 max=4]
* A
* B
* C
* D
[/poll]
I created exact same poll on try and it’s working as expected: https://try.discourse.org/t/polls-are-broken/601
I wonder if polls break when the post is in approval queue? 
(Joshua’s poll topic on try was in approval queue and I approved it)
Does rebuilding the HTML fix it?
Nope, tried that already.
If this is an approval issue it is ultra low priority
Are we sure this is an approval issue? Arpit seemed to be thinking out loud, not confirming…
Meta and try run the same code.
Understood. Polls seem to be working fine here and on try at the moment - I’m concerned if the issue was approval, or something else (TL0, network, etc.)
@jomaxro I managed to repro this locally and I think you’re right that posts with a poll in the approval will result in the poll being permanently broken even if we try to rebake it. I’m looking into the root cause now.
