VFB: Some themes cause forms to be hidden

Some themes cause Visual Donation Form Builder forms to be visually hidden. The workaround is a very small CSS snippet. GiveWP form widths are dynamic, and in cases like this it seems that forms load faster than the containing element.

In some cases it only happens on smaller screens, but in others it happens no matter the screen size.

The CSS workaround can be added anywhere custom CSS for the theme is added:

.root-data-givewp-embed {
    width:100%;
}

Astra and Avada are the most common themes that have this issue.
