summary: IE-9, use any editor toolbar button that insert text cause the whole page to scroll to top. if you are in "show preview" or "show diff" mode, it means you have to scroll back down to see the editor, because the preview/diff push the textarea lower on the page.
reproduction instruction:
- Use IE-9
- make sure you are not in "compatibility mode" (important! this does not happen in "compatability mode")
- go (as registered or as anon) to nlwiki, enwiki, hewiki or arwiki
- press "random article" enough times to find an article longer that one screen (i.e., an article where the vertical scrollbar shows for the article itself)
- go to "edit"
- press "show preview". now, in order to see the edit window, you need to scroll down.
- press any of the toolbar buttons that add text to the edit window. note that the page scroll to top, and you do not see the edit window any more.
the whole page scrolls to the top, and you have to scroll back down to see the edit textarea again.
a workaround is to use "compatibility mode", but on any RTL wiki, using compatibility mode means you have to resort to "old" (non-beta) toolbar, which means anons lose the toolbar completely, because of bug #34885.
