I remember experiencing this before with mapbox. When I click any of the first 2 buttons on the footer (montacargas, plataformas), it makes visibles the PDFs icons and changes the text inside each symbol.
Each row is contained inside a group
Inside each row, the PDFs icons are separated by individual IDs
rowA-1, rowA-2, rowA-3...
rowB-1, rowB-2, rowB-3...
rowC-1, rowC-2, rowC-3...
Each one of this PDFs icon / symbol have the pdficons class.
Well, the thing is that the text inside each symbol is not immediately visible, ONLY until you resize your browser is when the texts appears.
When I experienced this with map box, I resolved it by animating the size of the container where the map box is loaded, but here I can not resolve it that easily and still I believe there should be a more… elegant solution.

This is how it should look when loaded, but the text always appears blank, this happens in both Safari and Chrome.
And even after resizing the browser, if you pick other option in the menu, still some icons refuse to display the text container.
