Illustratr and the Audio shortcode in the Visual editor

A weird scrolling effect occurs when a recording is inserted with the [audio] shortcode in the Visual editor.

For some reason, the admin script keeps increasing the height of the audio player representational element in the editor which causes the content section to keep growing constantly, pushing lower content out of view and making the admin menu on the left and metaboxes on the right to scroll upwards.

At the bottom of https://vks11510.ip-37-59-121.eu/test/sample-page/ I posted a screen cast that shows the effect: I insert an MP3 at the top of that very same sample page (on a fresh site w/ only Jetpack and Illustratr activated) and after a few seconds I try dragging the scroll bar back up (2X) and finally all the way down.

Note: I tested this is in Chrome and Firefox on Ubuntu Gnome.
