`BUGFIX: Boot media module flash-messages correctly if rendered outside Neos module <https://github.com/neos/neos-development-collection/pull/5528>`_
-----------------------------------------------------------------------------------------------------------------------------------------------------

Solves the bug described in https://github.com/neos/neos-development-collection/issues/5379#issuecomment-2701041702

Previously only flashmessages in the Default template (e.g. on show) where shown but neither for editing or uploading

Flashmessages in the media module are not shown for all actions if the media module is booted within the Neos ui.
The current error for ``edit`` or ``new`` action is that ``this.container`` (``#neos-notification-container``) is null and thus no flashmessages can be rendered in the dom:

https://github.com/neos/neos-development-collection/blob/`c7be41ac865e096b62a019f3cf700222834b29f6 <https://github.com/neos/neos-development-collection/commit/c7be41ac865e096b62a019f3cf700222834b29f6>`_/Neos.Neos/Resources/Public/JavaScript/Components/Notification/Toast.ts#L39

The mentioned container is normally created by js itself as child to ``#neos-application``

https://github.com/neos/neos-development-collection/blob/`c7be41ac865e096b62a019f3cf700222834b29f6 <https://github.com/neos/neos-development-collection/commit/c7be41ac865e096b62a019f3cf700222834b29f6>`_/Neos.Neos/Resources/Public/JavaScript/Components/Notification/Toast.ts#L24

But the ``#neos-application`` is only rendered by the Backend Module Index template from Neos:

https://github.com/neos/neos-development-collection/blob/`89d4c84c5640a49867d56592b6def1a2c6e5db0d <https://github.com/neos/neos-development-collection/commit/89d4c84c5640a49867d56592b6def1a2c6e5db0d>`_/Neos.Neos/Resources/Private/Templates/Backend/Module/Index.html#L90


As the Media Ui provides a layout for the case of being rendered in the Neos backend module and for plain rendering as in the neos ui iframe (added via https://github.com/neos/neos-development-collection/pull/2171), the non module layouts must ensure that the shared javascript works by providing the desired dom structure.

- Module/Default.html
- Module/UploadImage.html
- Module/EditImage.html
- Default.html
- UploadImage.html
- EditImage.html


The flashmessages for ``showAction`` (e.g. default layout) work already in the neos ui as two changes https://github.com/neos/neos-development-collection/pull/5133 and https://github.com/neos/neos-development-collection/pull/5117 provided a fix to make the flashmessages work by ensuring ``<div id="neos-notification-container">`` is present.


This pull request extends the fix of providing an ``#neos-notification-container`` container for the ``UploadImage`` and ``EditImage`` template:
