+the tile title bar is 5 (top border) + 12 (title, buttons) + 5 (bottom padding) px = 22px
+the body is assumed to be 300px (assumed by at least the sticker pickerm, perhaps elsewhere),
+so the body height would be 300px - 22px (room for title bar) = 278px
+BUT! the sticker picker also assumes it's a little less high than that because the iframe
+for the sticker picker doesn't have any padding or margin on it's bottom.
+so subtracking another 5px, which brings us at 273px.
