Problem if twocomponents are added in VERY quick succession.

Overview

NOTE 1: It's unclear if this can happen outside of automated tests - prioritize accordingly

Note:2 this was discovered with the video component in canvas_test_sdc - we aren't yet sure if it occurs with other components

If an e2e test adds two video components consecutively, there can be problems with the form element changes properly updating the preview. While this would likely occur outside of e2e tests, it is difficult (perhaps impossible) to add them quickly enough to create the problem

For the e2e test where this problem was occurring, is was fixed by adding a non-video component between adding the first and second videos.

    cy.insertComponent({ name: 'Video' });
    cy.insertComponent({ name: 'Hero' }); // Adding me fixes it.
    cy.insertComponent({ name: 'Video' });

Proposed resolution

User interface changes
