 /**
- * Fixes textarea scrolling bug (bug #19334)
+ * Fixes textarea scrolling bug (bug #19334).  The bug only occurs when a
+ * percentage width is given, so instead of width: 100%, use min-width: 100%;
+ * max-width: 100%.  We also need to give a fixed width for the actual width
+ * property for the hack to work, although the actual value (500px here) ends
+ * up being ignored; min/max-width take precedence.
+ *
+ * More info: http://grantovich.net/posts/2009/06/that-weird-ie8-textarea-bug/
