Modified bug description.

** Description changed:

- The browser on my Ubuntu Phone (Meizu MX-4, OTA 15) does not open self-signed 
https-secured sites correctly. The browser presents the option to go back to a 
safe site or continue anyway. If I choose continue anyway, it starts to load 
the site, but never completes. After some time it stops loading and displays a 
rather incomplete version of the site. It is clearly composed of only some of 
the pages' elements and incomplete.The amount of the page that is displayed 
varies from time to time.
+ The browser on my Ubuntu Phone (Meizu MX-4, OTA 15) does not open some 
https-secured sites correctly, such as https://www.amazon.com or 
https://www.amazon.de. The browser presents the option to go back to a safe 
site or continue anyway. If I choose continue anyway, it starts to load the 
site, but never completes. After some time it stops loading and displays a 
rather incomplete version of the site. It is clearly composed of only some of 
the pages' elements and incomplete.The amount of the page that is displayed 
varies from time to time.
  It appears that transmission times out while loading the page.
- One common usecase of self-signed certificates is webinterfaces of DSL or 
cable routers, such as the popular fritz box.
  Test case:
- 1) Try loading the web interface of my router: https://rkupper.no-ip.org/
-    You should see the login page of a fritz box router.
- 2) Try loading the web interface of my nextcloud 
instance:https://rkupper.no-ip.org:444/
-    You should see the login page of nextcloud
- Observe that the appearance of the pages varies every time, depending on how 
much of the site was loaded. Observe that pressing the login button does 
nothing – probably because the scripts have not been loaded.
- I have tried other self-signed sites, and am confident that it is not a 
problem of my server.
+ 1) Try loading https://www.amazon.com. Observe that webbrowser-app displays 
warning about invalid certificate, without any apparent reason. Chose  
"continue anyway". Observe, that the site is only incompletely loaded and 
unsable.
+ 2) Try loading the web interface of my router: https://rkupper.no-ip.org/. 
This site uses a self-signed certificate, which is correctly displayed as a 
security risk. But self-signed certificates are a common use case on DSL or 
cable routers' web interfaces. Choose "continue anyway". You should see the 
login page of a fritz box router. Observe that the site is incompletely loaded 
and the login button does nothing at all.
