Links to the anchor on the same page breaked by Opera 8.50

I just accidentally found a regression bug in Opera 8.50.
Go to this page and click to search link (on the left top corner of the page). Browser will scroll the page to the wery bottom (to the search section). Than scroll page to the top and try click on the search link one more time – in Opera 8.50 it doesn't work (I tried Windows and Mac versions). Opera 8.02 do this just fine along with all my browsers on desktop.
Will post this bug on Opera forum shortly.
Update: Didn't fixed in Opera 8.51, work fine in Opera 9 TP1.
