Steps to reproduce:
- Create a page - default Eng page
- Click on the Information tab
- Click on each of the Translations pages French, Romanian and add content to them
- Access the Home page and change the wiki language to FR from the Drawer
- Access the FR page, newly created
- Click on Modifier
Expected results: The page can be edited in the selected language with the in-place editor.
Actual results: The page edited appears as the default ENG one.
NOTE: It appears that the wiki language is changed as selected only on IE11. On Chrome 81 and Firefox 75 the language is not kept when selecting from Drawer and changing the page like in XWIKI-17280.
