Bug ID: 61937 Summary: Auto scrolling badly breaks when writing "over the edge" (end of page) Product: MediaWiki extensions Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: major Priority: Unprioritized Component: Flow Assignee: wikibugs-l@lists.wikimedia.org Reporter: eduard.bra...@gmx.de CC: ebernhard...@wikimedia.org, mpinc...@wikimedia.org, pandiculat...@gmail.com, sp...@wikimedia.org Web browser: --- Mobile Platform: --- There seems to be a major bug with auto scrolling that starts when one is writing "over the edge" of the currently visible browser viewport. Steps to reproduce: - Visit a permalink of a topic (problem might be exclusive to topics as I can't reproduce it right now on a whole board) - Click "Reply" or the reply box at the bottom - Now start entering blank lines (just keep repeatedly pushing the enter key) - At some point the lower edge of the input field reaches the bottom of the currently visible browser viewport - Keep entering newlines (or maybe also some text from time to time to be able to better observe the problem) Expected behaviour: - Flow should keep the active line (therefore the last line if you followed the steps above) in sight, therefore at the bottom of the page. Actual behaviour: - At some point (soon after reaching the original end of the page) the automatic scrolling goes totally crazy. - It starts with the text jumping around by some pixels every time one is entering a character - Soon after the whole page is jumping around by multiple lines whenever entering a character - the active line is only quickly in the visible browser viewport when entering the character; quickly after the viewport is jumping back up the page and the active line is hidden. The above occurs for me on Windows 7 using Firefox 27.0.1 -- You are receiving this mail because: You are the assignee for the bug.
