- * HTML5 placeholder emulation for jQuery plugin
- *
- * This will automatically use the HTML5 placeholder attribute if supported, or emulate this behavior if not.
- *
- * This is a fork from Mathias Bynens' jquery.placeholder as of this commit
- * https://github.com/mathiasbynens/jquery-placeholder/blob/47f05d400e2dd16b59d144141a2cf54a9a77c502/jquery.placeholder.js

+ * No-op for compatibility with code from before we used
+ * native placeholder in all supported browsers.
