Improper Handling of Pagination SEO

[winterk80]

Preconditions

Magento 2.1.x or 2.2.x

Steps to reproduce

Go to a category with 3 or more pages
Goto page 2
When you click back to page 1 OR click previous button it appends ?p=1 to the url

Expected result

?p=1 should not be appended to the url. This creates a duplicate page. Even though the url is canonical this degrades SEO page authority because you have created a duplicate page in Google and Bing's eyes by appending the ?p=1 to the url Should be the original page url without ?p=1 appended

Actual result

Magento appends a ?p=1 to the page one url and the previous button, creating a duplicate content problem.
This also creates a problem with rel="next" rel="prev" when you try to implement because magento is creating the duplicate page with ?p=1 for page one.
