Part of the work to improve reflow of the component. This helps to make all the footer buttons accessible on small screens and gives some extra breathing room to the body.

Rollout strategy

Testing & Reviewing

The CSS changes seem a bit esoteric, but are due to overflow: scroll not being compatible with justify-content: flex-end. flex-direction: row-reverse; flex-wrap: wrap-reverse; plus reversing the items is visually equivalent but compatible. The focus order keeps being the same.
