wkwebview engine - Ionic Cordova - iOS 12 and 13 pushing footer buttons beyond safe area

I have an app written in Ionic v1, Cordova, and AngularJS 1.5.3.

iPhones tested on: iPhone SE, iPhone 8, iPhone X, and iPhone XR.

For iOS 13.6 the problem occurs on: iPhone SE, iPhone 8, iPhone X, and iPhone XR.
iPhone X, and iPhone XR ( completely pushes the buttons out of view )

For iOS 12 the problem occurs on:

iPhone XR - somewhat occurs
iPhone 8 - does not occur
iPhone SE - does not occur
iPhone X - somewhat occurs

For iOS 11:

it does not occur on iPhone 8. There are no problems.
iPhone SE - no problems
It somewhat occurs on the iPhone X.
iPhone XR does not run iOS 11.

As the version of iOS increases, it seems to have more of an effect.

What my code is doing:
My page is for the user to enter an absence and they have the option of adding photo attachments. The attachment is just going to be added as an ion-item in my ion-list.

I have an ionic view and a footer with a button in it. When I add an ionic item to my ionic list, it seems to push the footer button down out of the "safe area" and it does so permanently.

Even if I go to a different page and come back again the problem persists. It also seems to permanently affect the "safe area" on the different pages of my app.

Problem: As the attachment list grows, it pushes the footer button down out of the safe area

How can I keep my button in my footer in place on the latest versions of iOS?


Code snippet:

Code Block 
		<ion-content class="has-header has-footer bg-stable" padding="false">
				<ion-list can-swipe="true">
						<ion-item class="flex-container-center" ng-repeat="attachment in attachments">
								<div class="flex-item-1">
										<img ng-src="data:{{ attachment.mediaTypeField }};base64,{{ attachment.imageDataField }}">
								</div>
								<div class="flex-item-big">
										<div>{{ attachment.filename }}</div>
								</div>
						</ion-item>
				</ion-list>
		</ion-content>
		<div class="bar bar-footer no-padding bg-bottom">
				<div class="button-bar">
						<button class="button button-positive" ng-click="book()">
								<span ng-i18next="SAVE"></span>
						</button>
				</div>
		</div>

css

Code Block 
body {
		padding: constant(safe-area-inset-top) constant(safe-area-inset-right) constant(safe-area-inset-bottom) constant(safe-area-inset-left); //iOS 11.2
		padding: env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);
}

html

Code Block 
<meta name="viewport" content="viewport-fit=cover, width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">

As I'm using cordova-ios 6.1.0 I'm using WkWebView only.

<platform name="ios">
