Here is a STR to reproduce this issue:

1. Launch the SMS app.
2. Press the "new message" button.
3. Tap the Composer so that the keyboard is displayed.
4. Press Home to go back to the homescreen.
5. Long press Home to show the Task Manager.

=> The screenshot only shows part of the app.

QA: can you please do a branch checks ? Thanks !

screenshot of issue

This issue is not a regression and occurs on all branches including on v18D-1 base image only. With keyboard on screen in Messages app, going Home and then bringing up Task Manager will show that Messages app's screenshot is not of the whole app.

See screenshot for bug behavior.

Note that this also impacts edge gesture, since the issue is with the appWindow's screenshot.

We probably need to make sure the appWindow is resized before we take the screenshot.
