Bug report

Though I have tested for #533 at pure environment by many times, but for now it truly doesn't work at production, which is a blocker of our next minor release.

Version

0.13.0 Pre-Release

Steps to reproduce

1. Create a new commit into master
2. Check out the website, you can find there is a new registered SW which is in waiting, but no any SW-update popup show up.

What is expected?

SW-update popup should be shown.

What is actually happening?

No popup was shown.
