Discussing this with @jamesbrumpton & @nataliesmart:
When the text for the link is exactly the width of the viewport and you hover/focus, the styling adds padding of 2px on each side and therefore pushes a word down onto the next line. This jump is quite jarring. [1]
However, we discussed how the inline link item is to be used within an article body only - so in a paragraph in the main body copy, or a paragraph within a caption (for an image or video) and in all these scenarios, the components have a minimum of 8px spacing on either side of the text. So this 'jumping' behaviour will not be seen in an Article. [2]
However, we should add a note to the Readme of this component, under usage, to strongly suggest margin or padding on the left and right of 2px or more, whenever using this in production.
