Just to confirm for me, voting is the only issue that's been reported so far? and testing that on my side..
I'm seeing the same issue on Safari browsers.
The same problem persisted on Chrome for me as well, although its using maybe not the most up to date version.
I think it's redundant now as im sure everyone is going to be experiencing the same example of the issue but yes, it looks like the image posted already:
I guess if we can't stop untoward upvoting in the system, then simply breaking it stops that problem
