Have found that creating, if possible, multiple different workarounds provides a means to locate additional bugs in an API, template basic UI's if needed, for the ability to describe how the procedure should ideally work in code.

For example, consider the specific timing of granting of permission to take a screen shot in relation to when the screenshot is actually copied from the screen. 

While trying to reproduce an unrelated bug using `getDisplayMedia()` recorded (using `MediaRecorder`) two versions of the code run with output at `console`. However, instead of the UI being closed before the first image is captured, the permission UI covering a substantial portion of the screen, is captured. Would the user expect the permissions UI to be captured as an image as the first frame? Without trying to create workarounds this screenshot proposal could become an API which captured the permission UI because no workarounds, directly relating to the prospective UI improvements, or related code which presents issues which could affect this screen shot API; that is, making certain that a screen shot does not mean capturing the permission UI as the first frame. What should the UI for a screen shot API look like and do - and not look like and not do?
