Device name: Nexus 5

From "Settings > About Chrome"
Application version: 53.0.2785.124
OS: Android 6.0.1

URLs (if applicable): tageswoche.ch

Behavior in Android Browser (if applicable):

When I visit mobile version of the above website, it hangs (on animation spinner) and I can't do anything. I tried to debug what's going on via remote debugger and I noticed that some requests are "pending" thus the website can't load properly. In Chrome beta (v 54) it works fine. I also tried to optimize the page a bit (I know it is not perfect) by moving some external resources loaded in document head.
Also in version below 53 it also worked fine. Any idea what has changed and how can I fix it now without waiting for v 54 release?



Steps to reproduce:
(1) Go to tageswoche.ch
(2) See that the page is not loading

Expected result:

Mobile version of the website loads fine.


Actual result:

Mobile version of the website hangs.
