Ionic 4 - Header going up

Hi, whenever I open the keyboard in my App or when I rotate my phone to horizontal and then back to the o vertical, my header goes up.

Is this an error with Ionic 4?

How is it possible that there’s no solution to this? How can this even be happening at a 4th version? I’ve seen workarrounds for ionic 3 with .scroll-content styles but that’s not here anymore.

Help please?

I’m not sure that the issue was resolved in v3?

I remember trying lots of things, like the ‘viewport’ options:

  <!-- Use viewport-fit=cover to fill the iPhone X notch and also prevent content going under the status bar (if it's translucent) -->
  <!-- More info: -->

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

And, it also affects the ‘footer’:

Rotate the screen (horizontal):

Rotate the screen (portrait):

And, opening the keyboard pushs up the ‘footer’:

Where do you put that? In the config.xml out of the platform tags?

I don’t have footer. Just tabs but nothing happens to them. Just to the header which goes up and stays hidden.
