Description

Documentation says: import Path -> "A static getter on the element class that defaults to the element HTML import document URL and is overridable. It may be useful to override importPath when an element's template is not retrieved from a or the element is not defined using an HTML import." can be found here, section: URLs in templates

But it seems that when using a component with inline template this importPath property is undefined.

研究方向
Investigate the importPath property in Polymer's element class. The issue mentions that importPath is undefined when using inline template. Look at the Polymer source code (likely in Polymer/polymer repo) to understand how importPath is set and if it relies on HTML imports. Check the provided repo (import path bug) to reproduce the issue. Consider examining relevant files such as lib/element/import path.html or similar.
