iron-elements and its dependencies are not compiled by polymer-cli due to import('@polymer/iron-behaviors') unable to resolve the module type "node".
Most of modules from iron-elements collection actually are written as es6 modules and only missing part is package.json module type properly set.
Some modules like iron-elements are not yet ported to es6 modules yet. Since iron-elements is just a dependencies aggregation, it should be a low hanging fruit to port.
Expected outcome
polymer 3 project build passed without compile errors.
Actual outcome
Could not resolve module specifier "@polymer/iron-behaviors" in file "C:\aWork\polymer3-vaadin14-portlet\modules\polymer-vaadin-portlet\src\main\resources\META-INF\resources\webcomponents\load-iron-elements.js"

Live Demo
https://github.com/sashafirsov/polymer3-vaadin14-portlet/blob/iron-elements-error/modules/polymer-vaadin-portlet/src/main/resources/META-INF/resources/webcomponents/load-iron-elements.js
has imports of modules incompatible with polymer 3 commented out. If uncomment, each line would produce the compile error.
Steps to reproduce
polymer build
