Description

[Serg [:g00g1]]

Attachment: bug_demonstration.mp4

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0

Steps to reproduce:

1. create new container
2. open encryp.ch (it's AAAA is 2a0c:b641:6f1:55:656e:6372:726f:6f74)
3. open new tab within the same container
4. open git.encryp.ch (it's AAAA is 2a0c:b641:6f1:55:6769:7465:6e63:7200)
5. firefox thinks that git.encryp.ch has IPv6 address 2a0c:b641:6f1:55:656e:6372:726f:6f74

Actual results:

IPv6 address of git.encryp.ch was consufed with encryp.ch one

Expected results:

This seems a lot like bug 1420777.
We want to fix it soon. The gist of it is if one domain returns a cert valid for the other, and there's an overlap in the DNS records of the domains, then they will be coalesced.
If that's not the case for you please let me know.
