Currently, we can write HTML statically to the title or body of the cards by going to the Cards Region Attributes-->Body AND Turn on "Advanced Formatting".
After we turn on "Advanced Formatting" a textarea is shown where we can enter HTML.
However, if we write the HTML dynamically in the SQL source of the cards region and reference it on this textarea such as "&MYHTMLCODE.", Apex shows the HTML code as plain text in the card body.
It would be great if Apex could interpret it as HTML instead of plain-text.
