Take a look at the GIF attached.
Here are the steps:
1. Create an area type, enable bounding box, click and drag a corner marker with Selection tool
2. Hold Alt + Shift to proportionally resize the area from its center
3. Change your mind!
4. Release Shift while still holding Alt and the mouse key — while still moving the cursor

Some splitting happens — the frame of the bounding box follows the cursor, but the rendered frame with the text stays in the previous registered location.

The faster you move the mouse — the larger is the gap.
When released, the text jumps into the position of the bounding box frame (that is not where it gets rendered).
