Research direction

Read Ember issue #19401 first to establish the breakpoint and source-map failure, then inspect ember-cli-htmlbars around the behavior discussed in PR #558. Reproduce the discrepancy and compare the mappings with the editor's expected locations; done means in-editor breakpoints resolve to the correct source positions without relying on the rejected approach.

Description

The bug is perfecly described in https://github.com/emberjs/ember.js/issues/19401

The issue belongs to ember-cli-htmlbars though and I believe we need an issue in this repo as well to help things move forward.

PR https://github.com/ember-cli/ember-cli-htmlbars/pull/558 is an attempt to fix this issue but does not seem to be the right thing to do.
