Wrong npm version is picked up by Intellij IDE

I'm working on Gradle project with Intellij IDE and having wrong npm version pickup issue when I try to set npm version outside of node folder in this IDE. (example test-node-plugin.zip)

I have node & npm version specify in build.gradle.

node {
	version = '10.16.0'
	npmVersion = '6.10.0'
}

So there will be 2 dedicated folders for nodejs & npm are generated inside .gradle folder, after I run npmSetup task. (see next screenshot)

By default IDE will pick both nodejs & npm version in nodejs folder (npm version is 6.9.0)

When I try to pick new version from outside folder (version 6.10.0 in .gradle folder) it still keeping version from nodejs folder, which is 6.9.0.

Do you have any suggestion on this? Would it make sense to update npm version in nodejs folder, let say I will do npm install npm@6.10.0 -g and don't need to refer to npm(outside) folder? IDEA team already close this issue as won't fix because they expect IDE has same behavior as terminal

Start with the build.gradle node configuration and the npmSetup task described in the issue. Reproduce the setup with npmVersion 6.10.0, then inspect how the generated .gradle npm folder relates to IntelliJ's selected npm path. Done means the configured npm version is consistently picked up outside the nodejs folder, with the behavior verified in the example project.
