When there is more text in a textarea than can be shown (i.e, whenever there is a scrollbar on the right of the textarea) AND the cursor is at the end of the textarea's inputted text, pressing right arrow returns the cursor to position 0,0 of the textarea. To reproduce: 1. type enough lines of text into a text area so that the top line scroll's past the textarea's view (these can be short lines, like "aaa"). 2. At the end of the last line, press the right arrow key. (This is particularly annoying when you go back up in a textarea to cut or paste or whatever, then try to return to the insertion point at the bottom and end up at the top somewhere).
