Jitter at end of navigation page transition

There is a slight jitter/pause at the very end of the animation/transition on the navigation to a new page on iOS devices.

Click on any row and watch the header title text jitter/pause slightly at the end of transitioning to a new page. The demos on ionic’s site are butter smooth, so it must be something I’m doing wrong. Does anybody have ideas of where to dig to resolve this issue? I’m hoping for a clue as to where I should start investigating to track this down.

I’m using public cdn ionic libraries:
https://cdn.jsdelivr.net/npm/@ionic/core/dist/ionic/ionic.esm.js
https://cdn.jsdelivr.net/npm/@ionic/core/dist/ionic/ionic.js
https://cdn.jsdelivr.net/npm/@ionic/core/css/ionic.bundle.css
