The project view shows srcs and headers as flattened list of directories when using source_group(TREE ...)

It seems that qtcreator 4.11 added support for the source_group command of CMake, which is great. However when using source_group(TREE ...) i expected to have a real tree in the projects view. Instead it shows a flattened tree with one entry per inner folder.

For example using

cmake_minimum_required(VERSION 3.15)
project(folderstructure)
set(files
  src/a/file_a.cpp
  src/b/file_b.cpp
  src/c/file_c.cpp
  include/a/file_a.h
  include/b/file_b.h
  include/c/file_c.h)
add_library(l1 SHARED ${files})
target_include_directories(l1 PUBLIC include)
source_group(TREE ${CMAKE_CURRENT_SOURCE_DIR} FILES ${files})

I would expect to have (And which is what i had up to qtcreator 4.10)

• l1
  • include
    • a
      • file_a.h
    • b
      • file_b.h
    • c
      • file_c.h
  • src
    • a
      • file_a.cpp
    • b
      • file_b.cpp
    • c
      • file_c.cpp

In qtcreator 4.11 i get

• l1 
  • include/a
    • file_a.h
  • include/b
    • file_b.h
  • include/c
    • file_c.h
  • src/a
    • file_a.cpp
  • src/b
    • file_b.cpp
  • src/c
    • file_c.cpp

 Which is IMHO much harder to read, therefore i would like to have again the real tree from the previous version, filled with the information from the source_group(TREE ...) call.

Additionally when i do not specify source groups at all, all source files and all header files are thrown together into one "Source Files" and one "Header Files" folder where all folder structure is completely lost. If possible i would like projects for which no explicit source groups have been set up to behave as before.

I hope i did not miss any option to achieve this.
