Comment (by azaozz):

 Replying to [comment:2 subrataemfluence]:
 > However, I believe why `window.tinymce.ui.FloatPanel` is showing
 `undefined` is more likely to be the area to inspect.

 Right, seems the `wp-before-tinymce-init` event fires too early. Switching
 to `tinymce-editor-setup` (fired when the `wordpress` plugin starts to
 load) fixes it.

 Going to commit this for easier testing, also pinging @westonruter to have
 a look if possible.
