When starting a devcontainer, The Kit detection is broken. At first, the Kits file only contains a qt detected file, but the cmake extension does not list any kits. Running "CMake: Scan for Kits" fills the kits with the default kits, but removes the Qt Kit. Running "Qt: Scan for qt Kits" does put the Qt kit into the kits json, but the cmake extension does not update.

Only after reloading the window ("Developer: Reload Window") all Kits are selectable.

See the attached "devcontainer.zip" for reproduction.
