Steps to reproduce

1.  Setup project with multi-tree languages support (each language has it's own branch in the content tree)
2. When the current language is different to the logged in user's language
3.  After adding / editing / deleting / reordering components on a page, changes are not directly visible as the content doesn't refresh (reload page).

.. Logs, screenshots, gifs...

Expected results

• Refresh page after editing as usual

.. Justify non-trivial expectations with a link to a doc or a relevant discussion.

Actual results

• System does not

Workaround

• No

Development notes

Customer investigated the behaviour and figured out that it came in with the following commit:

https://git.magnolia-cms.com/projects/PLATFORM/repos/ui/commits/88ee92b7f5084d86a7fd00202866c5cd75193f00

subAppContext.setAuthoringLocale(contextProvider.get().getLocale());

This has impact on line 272 in the following file:

https://git.magnolia-cms.com/users/apchelintcev/repos/pages/browse/magnolia-pages-app-compatibility/src/main/java/info/magnolia/pages/app/editor/PagesEditorSubApp.java

ObjectUtils.equals(authoringLocale, pageEditorPresenter.getStatus().getLocale())

It only happens in a project setup with multi tree (each language ha it's own branch in the content tree) and when the current language is different to the logged in user's language.

This issue might affect every project with newer Magnolia versions.
