Post History

I understand what is happening right here(with the counting). 

In Codegolf, sequence tag has 5 posts.

But, it only has 4 question

I was searching for the issue. What is wrong with the code? Then, I was reviewing posts on with that tag. If you check history of those posts than, you will see **@Razetime** had edited [a post](https://codegolf.codidact.com/posts/279253/history) multiple times. Usually, the number of sequence tag was $4. But, when **@Razetime** had edited that post once. The number became 4+1=5. When he edited that post again the number was as it is. Which means when you edit a post first time the number of question in that tag list will be increase. 

I think this will be very hard to solve. The number of sequence tag on following picture was taken from server.

 But, in `Posts tagged list` it was calculated programmatically. `mysqli_num_rows` that's what php programmer writes. While Codidact is written in Ruby. That's why sometime I can't understand code. 

**This answer will be helpful for Ruby programmer to work on [the issue](https://github.com/codidact/qpixel/issues/249).**
