AOS not triggering the last element of my page

This is:

• Bug

Specifications

• AOS version: latest
• OS: macOS
• Browser: Chrome

Expected Behavior

Just regular animations should trigger for a couple of elements on my page.

Actual Behavior

All elements trigger animation but the last few trigger with a delay and the last one doesn't trigger at all.

Detailed Description

I have a page with a decent amount of content so it's pretty long. The more I scroll down the more delay I get on the trigger of animations. It causes elements to appear late, slow or not at all.
