Missing right padding in the "Import symbol" example

The "Import symbol" and "Import directly with a jsr specifier" code snippets should have some right padding, similarly to how they have left padding. Ideally, it should be enough padding that (when scrolling all the way to the right) the "copy" icon does not overlap with the text.
