difference
not only the alignment as reported in Wikipedia is different, also the Liberation Sans font looks different.

Liberation 1 vs Liberation 2
Checking T253600 it seems they use different version of fonts: SVG-check maybe Liberation 1 but Commons uses Liberation 2

Liberation 1	Liberation 2	SVG-check	Commons

This looks like the text-chunk regression bug.

librsvg erroneously calculates the width of the whole text chunk as the width of the last tspan or #text node. In this case, the last #text node is ":", so librsvg believes the whole string should be offset from the anchor by half the width of a colon. That makes the text appear to start at the anchor; it looks left aligned rather than middle aligned.

So bug is a duplicate of T200443.

Close a duplicate failed. trying again.
