TYPO3 Core

When reordering inline records containing a rtehtmlarea field, the rtehtmlarea content stays hidden. We noticed this problem in several of our own extensions, in the example below I use the jfmulticontent plugin, but it's broken in every plugin I tried that has tt_content as inline content elements.

How to reproduce:
1) Install the jfmulticontent plugin: http://typo3.org/extensions/repository/view/jfmulticontent
2) Add an instance of that plugin to a page
3) Select "Inline content" in the view menu in plugin settings
4) Add two text elements to Insert inline content field
5) Move one of the records up/down
6) The result should be similar as shown in the screenshot
