Due to our very limited maintenance capacity, we need to prioritize our development focus on other tasks. Therefore, this issue will be automatically closed (see #15395 for more details). In the future, if we see the need to attend to this issue again, then it will be reopened. Thank you for your contribution!
@vbrin27 The 2.x branch is no longer supported. See #15344. You may want to try whether the master branch works for you (future version 3). It has installation instructions.
I am using babel polyfill && custom-elements.min.js for my website and I have concatenated both the polyfills in a single file.
When I try to run the testcases in PhantomJS(v 2.1.1) headless browser by loading this file in Karma testrunner, some errors are thrown which are not reproduced in other browsers.
The above issue is thrown in babel polyfill and if babel polyfill alone is used without custom-elements polyfill, there are no errors.
Error thrown:
The code which causes the error: (Line No: 5345)
Is there a way to solve this issue?
