Security popover for some sites switches from strong to none after reload
Hello, I've noticed that for some HTTPS websites, the security icon in the address bar and the associated popover switches from strong ("Your connection seems to be secure") to none ("[Website] has no security") just by reloading the page.
I've created a screencast reproducing the issue on one website that is consistently affected by this: https://todoist.com. However, while investigating this bug, I've noticed it on some other websites intermittently, such as on https://ca.yahoo.com/?p=us.
On the same websites, I see no similar issue on other web browsers, such as Firefox and Chrome.
I started looking through the code to see if I could help, but I only got as far as identifying that the EphySecurityLevel
seems to be changing from EPHY_SECURITY_LEVEL_STRONG_SECURITY
to EPHY_SECURITY_LEVEL_NO_SECURITY
(lib/widgets/ephy-security-popover.c).
Let me know if I can provide some more information to help diagnose this issue.
