ADMIN EDIT
When the component calculates the size of the chunks it doesn't seem to use invariant culture so when the decimal separator is a comma `,` it puts that comma in the CSS rule, which the browser can't parse and the chunks have wrong sizes which makes them invisible.
Reproducible plus CSS workaround
