Typically PX Engagements retain their original size as shown in the editor, which is then shown to end users.
At times if a tooltip is left or right position biased , and being close to the viewport edge of an engagement creator’s screen, if an end user viewing it has a smaller screen in the end, things can go off the viewport like below.
It is desired to have some configuration to control over the responsiveness aspect of engagements. Maybe if the screen is two small, go ahead and do word wrap to fit or remove an image within the engagement or remove certain text as things get smaller. etc.
