Description beanbo 2024-04-21 20:36:09 UTC 
SUMMARY
KMail ignores "Allow messages to load external references from the Internet" setting in some rare circumstances.

STEPS TO REPRODUCE
1. Make sure you have a firewall or some other method to see the outgoing connections
2. Go to setting and disable the setting "Allow messages to load external references from the Internet"
3. Go to message list and preview HTML message which contains the following code inside <body> section:
<link href="https://fonts.gstatic.com" rel="preconnect">

OBSERVED RESULT
There is a connection attempt to fonts.gstatic.com:443

EXPECTED RESULT
No connection attempt should be initiated
