Page and Page Translation lists can not be collapsed/expanded independently
In the list module when you collapse/expand the "Page Translation" list, it will not be persisted. Instead it seems that it will always take over the state of the "Page" list.
Reproduce in a multi-language installation:
- Open a page in the list module that has translations and subpages. It will have “Page Translations” and “Page” record lists.
- Collapse the “Page Translation” list by clicking the little “up”-chevron in the top right.
- Refresh the module. “Page Translations” is not collapsed.
- Collapse the “Page” list.
- Refresh the module. Both lists are now collapsed.
