It looks like the SVG has just been exported at a width much narrower than the text. If you inspect the SVG on the second link you posted, you can edit the `width` attribute to something like 200 and see the full text.

Normally, when exporting SVGs for the web, you would convert the text to shapes. That way, people don't need a version of the font you've used and you can guarantee it looking the same across browsers.
