+#' @note grid, which marquee, ggplot2, etc are build upon contains a bug that
+#' means that the height of a grob is calculated before the grob knows it's
+#' width. The result of this is that if the width of an `element_marquee()` is
+#' `NULL` (the default), the text may overflow its allocated space with an
+#' additional line. Unfortunately there is no great fix for this, other than
+#' eyeball the width it has available and pass that to the element (e.g.
+#' `element_marquee(width = grid::unit(10, "cm"))`)
