Solid icons are identical tot non-solid

[FDelporte]

The following code:

        spanViews.add(LineAwesomeIcon.EYE.create());
        spanViews.add(LineAwesomeIcon.EYE_SOLID.create());
        spanViews.add(LineAwesomeIcon.THUMBS_UP.create());
        spanViews.add(LineAwesomeIcon.THUMBS_UP_SOLID.create());

Results in the following output:

While expected result is that the second and fourth icon would show as solid (filled).
Using this reference: https://fontawesome.com/v5/icons/thumbs-up?f=classic&s=solid

The problem is probably related to the use of the SVG-images without the classes as defined on https://icons8.com/line-awesome/howto

Icon can have 3 styles: regular, solid or brand. For each style there is a corresponding class: lar, las or lab.
Wherever you desire to place an icon simply insert the code below and change the class names (laX la-XXX) to correspond to the icon of your choice.

Yeah, sounds odd. But it is equally odd on https://icons8.com/line-awesome if you look at the eye icon. There is the regular and solid variant shown but both look the same
