Current Behavior

Using a tabbed app in the mobile browser the ion-header is being pushed off the top when the mobile keyboard opens. Please note this issue only occurs when fullscreen is set to true.

Expected Behavior

Header stays positioned at the top.

Steps to Reproduce

Hello.

To create the bug:

1. Create tabbed app for a mobile browser
2. On a tab page place a ion-header and ion-content with fullscreen set to true
3. Add a div to the tab page with a view height of roughly 70 depending on your device
4. Add a ion-input to activate the mobile keyboard
5. ion-header will get pushed off the screen

Sample code below:

<ion-header [translucent]="true"> <ion-toolbar> <ion-title> Tab 1 </ion-title> </ion-toolbar> </ion-header>

<ion-content [fullscreen]="true"> <div style="height: 70vh"> Mobile Device Fullscreen Header Bug - [fullscreen]="true" </div> <ion-item> <ion-input placeholder="Click Here - Watch Header Disappear"></ion-input> </ion-item> </ion-content>

Thanks! I can reproduce this behavior. This appears to be caused by https://github.com/ionic-team/ionic-framework/issues/18532, so I am going to merge the two issues. The linked has to do with Cordova/Capacitor apps, but it is the same problem in a web browser as well.
