TYPO3 Core

In v13 if backend_layout is set, this does not change the layout in the page module.

how to reproduce:

1. add tsconfig from below in tsconfig
2. save, and select tsconfig on page

mod.web_layout.BackendLayouts {
  exampleKey {
    title = Example
    icon = EXT:example_extension/Resources/Public/Images/BackendLayouts/default.gif
    config {
      backend_layout {
        colCount = 1
        rowCount = 5
        rows {
          1 {
            columns {
              1 {
                name = Keyvisual
                colPos = 2
              }
            }
          }
          2 {
            columns {
              1 {
                name = Content
                colPos = 1
              }
            }
          }
          3 {
            columns {
              1 {
                name = Footer
                rowspan = 3
                colPos = 3
              }
            }
          }
          4 {
            columns {
            }
          }
          5 {
            columns {
            }
          }
        }
      }
    }
  }
}

I couldn't reproduce it in v12 in a project but suggest to be in sync with v12
