Make the demos show their content fully in the guides

Description

Some of the demos are added to guides, but they are cut in a way that makes the DX rather poor. We should resize the example's element to enhance the guide.

Screenshots

(more than half of the demo is under scroll, plus it is covered by the buttons)

Start by opening the demos linked in the Custom functions, Advanced usage, Batch operations, Sorting data, and Internationalization guides, then locate the embedded example elements and their sizing. Done means the demo content is fully visible without unnecessary scrolling or being covered by buttons across the listed pages; verify the result in Chrome at the stated zoom and scale.
