Version of node in Docker image electron-builder:wine not updated

As far as I can understand the version of node.js has been updated in the base Dockerfile of electronuserland/builder to version 12.13.1 since quite a long time. I assume the concerned Dockerfile is this one.

Yet when I check the version of node with this command (as of 17 December 2019, without any cache):

docker run -ti electronuserland/builder:wine sh -c "node -v"

I get this output:

v11.10.0

According to Docker Hub this tag was published only a few days ago. I assume it is kind of a problem somewhere in the list or Dockerfiles inheriting from each other. Notably the Dockerfile for wine inherits from the electronuserland/builder:latest image that was not updated since 10 months.

I ran into this issue today. What solved for me was to download this repo, run ./docker/build.sh and then inside the container node --version returned v12.14.1 as it should.
