You are right in 50%, and I too hate the size of the poll area compared to the rest of the post. Unfortunately there is no size control for it. If there was a compact look to choose I would definitely switched that.
(I will submit suggestion for that 
Don’t worry not in this section. This one #technology-research:feedback). And here it is.
Now, be honest with me:
Are you 200% positive you would not get excited if @CCP_karkur clicked (or better yet connected this thread to some triage backlog via bot that sniffs for staff-only polls and clicks accordingly) on one of those damn polls I so stubbornly and meticulously weave into my QoL suggestions?
If anybody else would like to place polls in their QoL’s, here is the code I place in mine:
[poll type=regular results=always chartType=bar groups=staff]
# Text that follows 'Suggestion: ' from the very first line of the suggestion post
* In review
* Rejected
* Accepted
* Released
