TYPO3 Core

When you have a record with tabs and an RTE textarea element on more than one tab. Then the RTE elements which are not on the current tab will be way to long.

Example screenshots:
RTE on first screenshot (Tab which is open when you edit the record) has the normal expected height.
RTE on 2nd screenshot is abnormal long (>1000px).

TCA field configuration for these RTEs:

            'config' => array(
                'type' => 'text',
                'eval' => 'trim,required',
            ),
            'defaultExtras' => 'richtext[*]:rte_transform[mode=ts]'
