Problems on site forum.vivaldi.net

[ghost]

Trying to read a topic on forum.vivaldi.net (for example https://forum.vivaldi.net/topic/22712/issues-with-vivaldi-password-manager) leads to incorrect behaviour.

AP scrolls through 3 consecutive pages, starting the forum thread anew on every page. Actually (currently) the topic only has 1 page; AP "reads" 3 pages.

Tried on Vivaldi 1.13 and Vivaldi Snapshot 1.14 on OS X 10.12
