(iOS) Undesired scroll bounds/limits when keyboard is up (ionic-exclusive?)

[Lindsay-Needs-Sleep]

When I have a long page with text input fields (long enough to scroll a decent amount)

• If I select an input near the bottom of the page I am unable to scroll all the way up. (Or vice-versa.)
  • After being denied scrolling all the way up (or down) once, it then lets me scroll the full length of the page.

Environment

iOS 12.2 (iPhone X emulated), 13.3.1 (iPhone 6s real), 12.4.5 (iPad mini 2 real)
slightly modified ionic tutorial project
cordova-plugin-ionic-webview 4.x

Investigation

• When using cordova-plugin-ionic-webview 4.x on a pure Cordova project it is fine.
  • Maybe (quite possibly) I just don't know what I am doing with ionic and missed a configuration option or something
• When I install cordova-plugin-ionic-keyboard this issue disappears

NO cordova-plugin-ionic-keyboard

See how the app apparently thinks I've reached the top on the first attempt at scrolling

Thoughts

Is cordova-plugin-ionic-keyboard maybe just covering up the issue?

• I say this because when cordova-plugin-ionic-keyboard is included, the keyboard pops up, but the content does not shift up, (and unfortunately the keyboard covers the selected input).
  • Maybe the content shifting up a bit throws off the scroll bound limits somehow
• Maybe this is related to the shmorgishborg of issues surrounding this issue? Though this focuses on keyboard dismissal issues... not keyboard pop-up issues
  • The shmorgishborg has been slightly documented in PR fix(ios): avoid app scrolling to top on keyboard hide #533
• Not sure why it only happens on an ionic project and not a cordova one. :/

Is this just me? (If so don't worry about this issue, because I have no intention of actually using ionic. :p) (Just curious because I was working on related stuff)
Any ideas?
