'First Unread Post' button?

[ButtermilkJack]

I just noticed that if someone has just started a thread, and there is only one post, when you navigate to it from the 'View first unread post' button on the homepage the browser will jump right down to the bottom to the quick reply section. Whereas in threads with more than one post it finds the last unread post as intended.

Is this generally what happens or is it browser specific?

I think its a glitch in some add-on package.
The url has an anchor at the end.
