If you look at the wikipedia.org portal in an RTL language, you'll see that the project icons are placed quite far from the text that describes them, but very close to the text that describes other projects in the adjacent column. So, for example, the label for "Commons" appears next to the icon for Wikivoyage, and the label "Wikivoyage" appears next to the icon for Wiktionary.

The icons must be moved to appear next to the labels that correspond to them.
