Description
When evaluated ARG contains another ARG reference it expected to be fully expanded.
Example line: https://github.com/ohhmm/openmind/blob/e7e9170d4ebb86e32112ae0b4397db51925478f6/.devcontainer/Dockerfile#L4
ARG LLVM_MAJOR_VERSION=17
ARG LLVM_FULL_VERSION=$LLVM_MAJOR_VERSION.0.6
Hovering LLVM_FULL_VERSION hints $LLVM_MAJOR_VERSION.0.6 but 17.0.6 is expected.
