TYPO3 Core

I have the same bug in TYPO3 7.6, this worked like a charm in 6.2 though

It seems like this is a general problem with Iframes that are moved in the DOM. An Iframe loses its state and is usually refreshed. But since the RTE is dynamically created, there is nothing to refresh.
In TYPO3 6.2 the code was similar, did something change in the RTE handling in that area? Like a regular check if the RTE instance is still working or needs to be reinitialized?

I have to correct myself: this did not work in 6.2 either, but the Iframe sourcecode does not show up, it's just empty. To reproduce the bug, the inline element with the RTE needs to be moved, not another one pre- or appended. Is the only solution to trigger the RTE initialization again? The content of the textarea is not lost, just maybe the cursor position.

This also happens with the CKEditor and t3editor as soon as open inline elements are sorted and flex sorting.

This is a known problem. an iframe can not be moved within the dom without reloadind / re-init.

A solution could be to trigger an event after resorting the inline elements. Each element can listen to this event and re-init if required.

The following element need the possibility to re-init before this can be fixed:

- t3editor
- rtehmlarea
- ckeditor

that's an issue with re-init of moved iframes. guess we will not be able to fix that until 8.7.0 lts anymore.
