[Tripuls-Magento]

Preconditions (*)

1. magento 2.3.4
2. create cms-specificlayout file in your module/theme for home

Steps to reproduce (*)

1. Add a cms_page_view_selectable_home_somechanges.xml as described in https://devdocs.magento.com/guides/v2.3/frontend-dev-guide/layouts/xml-manage.html
2. Edit the home page in the backend to use the specifc Layout (CMS->Pages->home>edit->design->select "somechanges" ..)
3. Save.
4. Clear layout-cache
5. Refresh home page

Expected result (*)

1. Specific layout changes from cms_page_view_selectable_home_somechanges.xml should be applied

Actual result (*)

1. Changes have no effect

Workaraund:

Place a second file cms_index_index_selectable_home_somechanges.xml in your theme/module and the changes are applied.

Backgraund:

The DefaultLayoutHandle differs on the homepage from regular CMS_Page_View, since the full action name is cms_index_index
\Magento\Framework\View\Result\Page::addPageLayoutHandles
(\Magento\Framework\View\Result\Layout::getDefaultLayoutHandle)
