Screen Capture of Menu Scrolling Issues

SUMMARY
***
When using an app launcher other than Application Launcher 2.0 (This would include "Legacy Application Launcher" (Legacy Kickoff), "Application Dashboard", and "Application Launcher (Unibody)"), scrolling in the menus is buggy on Wayland. The scroll speed is super slow and instantly goes back to the top of the screen when the bottom of the list is reached. This does not happen on Xorg. 
***


STEPS TO REPRODUCE
1. Use a launcher other than "Application Launcher 2.0"
2. Scroll in a vertical menu to the bottom of the list
3. Scrolling is very slow and it will pop back to the top of the list when the bottom is reached.

OBSERVED RESULT
Scrolling is very slow pops back to the top of the list when the bottom is reached in launchers other than "Application Launcher 2.0"

EXPECTED RESULT
Scrolling should be faster and consistent to the way it works in "Application Launcher 2.0". Scrolling to the bottom of a vertical list should not send a user back to the top.
