Status: RESOLVED DUPLICATE of bug 334256

In a textarea if you attempt to set the selection to the beginning of the next line, and that line is empty, then the selection is sometimes set to the end of the current line.

This is somehow dependent on previous navigation actions.  For example, if the last act of navigation is left arrow, the caret will wind up on correctly on the  next line.  If it is a right arrow, then it only goes to the end of the same line.  A Home seems to make it work, while a ctrl+home causes it to stay on the same line.

Note that if it "doesn't work" and the caret winds up at the end of the first line, then pressing alt+n again will place the caret at the beginning of the third line.  But this is expected because .selectionEnd has told us it's at the beginning of the second line so that its expected next position is at the beginning of the 3rd line.

This is the same as bug 334256, which is now fixed (on trunk).
