www-apps/guacamole-client emerge fails on network sandbox issue

[pcrow]

I'm building on arm64, and during the build, maven tries to download node-v18.18.0-linux-arm64.tar.gz which is blocked. The ebuild succeeds if you use:
FEATURES=-network-sandbox emerge guacamole-client
I don't know if emerging nodejs first would help, or if this is something specific to arm64.

try installing nodejs first
You can send me a complete log of the installation process /var/tmp/portage/www-apps/guacamole-client-1.5.5/temp/build.log and your system with emerge --info

Interesting. Nodejs is not a dependency, and nothing else I have on the system needs it. From the error, I'm assuming I should install net-libs/nodejs-18.20.3, or does it matter?
