heading of editor page only partially on screen

As you can see from the screen shot both the microbit oval with 2 dots and python snakes are obscured.

Is it possible to scroll this heading off screen to create a larger programming area. With my default keyboard i can only see 3 lines of listing. With a 'programmers keyboard' which has configurable size, I can see 5 lines.

Functionality similar to this page is what i desire. So i can scroll within a textbox and scroll the full page.

Device
Samsung j5 mobile phone
Android version 8.1.0
With samsung experience version 9.5
Chrome version 75.0.3770.101

No source file or test is named. Reproduce the editor page on the listed Samsung J5 and Chrome setup, then trace the mobile heading and scrolling layout; done means the heading can scroll off-screen while the editor and full page remain scrollable, exposing more programming lines.
