Input textarea with ion-footer-bar in ionic is behaving erratically

[stib]

In updating my ionic-v1 app recently my keyboard functionality in ion-footer-bar in the messaging window started behaving erratically.

When I tap on the text input screen for the messaging section of the App, the keyboard shows up but my page header scrolls away and when I type the message text it does not appear in the input textarea. Tapping the input area again few times jumps/scrolls the screen around.

The issue has also been described here ionic-team/cordova-plugin-ionic-keyboard#47 and ionic-team/ionic-framework#12844

This issue is for iOS only - Android side works fine.

I have tried proposed solutions like adding the following to my config.xml

<preference name="KeyboardResize" value="true" />
<preference name="KeyboardResizeMode" value="ionic" />

but that hasn't helped. Those solutions seem to be for later versions of ionic and I am on ionic-v1.

Expected behavior will be for the input textarea in the ion-footer-bar to behave normally.

I am stuck on this issue for almost a week. Look forward to any help or pointers to help address this issue.
