Describe the Bug
The bug deals with the placement text in the ion-input component. The placement text jumps when tapped on either device or emulator.

Steps to Reproduce
Steps to reproduce the behavior:
ionic start InputScrollJank blank
cd InputScrollJank
Edit ./src/pages/home/home.html to include an ion-input.
example:
<ion-item no-padding no-line> <ion-label stacked>IDENTIFICATION NUMBER</ion-label> <ion-input formControlName="vinInputFormControl" placeholder="Enter VIN" clearInput> </ion-input> </ion-item>
ionic run ios --device
tap on the ion-input. This must be done on a device or emulator.
Your placeholder text will flicker/jump.

Related Code
Related code may come later if needed.

Expected Behavior
It would be expected that the placeholder would be visually smooth as in the browser.

Additional Context
I have viewed Issue #10272 as well as Issue #10257 (IOS setFocus on input make screen jump). Both of which have been closed, but neither match this issue. #10272 matches closely, but the issues are slightly different.

Also, I've uploaded a screen recording of the problem here

Thanks for the issue! Going to close this as a duplicate of #15888.

I see #15888 and it is not the same issue. Please note that the issue I am explaining is the jumping action of the placeholder text due to the keyboard popping up.
