Switching pages in the emoji widget is unbearably slow

Describe the bug
This has been brought up several times in the past but has not gotten its own thread. At this point I think it's warranted.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.): Touch Bar

Device information:

  • Type of Mac: 2016 15" MBP
  • macOS version: macOS Mojave beta 5
  • BetterTouchTool version: 2.536

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
Previous discussions converged on eliminating the built-in pagination entirely as the solution to the issue and displaying a single continuous list. I'm in favor of such a solution.
