drag.ts

/**
 * In this test suite there's two sets of each test, one without and one with the `layout` prop.
 * This is because when a component has the layout prop applied, we apply drag to the bounding box
 * and when it isn't, we apply it to the x/y transform.
 *
 * Descrepencies between the expected values in the two sets of tests are *something* to do with how
 * pointer events are being resolved with Cypress, but a manual check will verify that both drag modes
 * are working visually the same.
