I found that it's a issue on my thread,such as How to creating local link on my blog article ?
It hasn't jumped to bottom when clicking the top of 'Latest reply' on the browser of Google Chrome 63.0.3239.108 (32bit) or not jumped to top when clicking the bottom of 'Go to original post' and which on the browser of Firefox (57.0.2 - 64bit) or IE11 (11.0.9600.18860) Updated Version:11.0.49 (KB4052978) is okay.
Afterwards,I also found that all of my threads - only one page (not 2 page and more) haven't jumped and more than one page's threads (such as Why tablespace SYSAUX's used percent has been increased fast ?) are normal on these browser - Chrome,Firefox and IE11.
Maybe I guess that it's a bug on Chrome.
Please try it,thanks!
Thanks for your reminding,I am careful in future - never '@Mention'.
