Column selection starting from empty line is not honoring starting column position

Don't forget the empty line at the end.

Move mouse to the middle of that empty line, hold Alt and start to drag to make column selection (rect selection).

Expected: only the content within the visible rect you're drawing should be selected.

Current: the selection includes the empty last line, so selection is not what user expects.

You can see expected behavior in Sublime (it uses Shift + right click instead of Alt + left click):

as you see, i don't reprodiuce it.

i have option 'caret after eol' on.
it may affect.
and option for 'primitive column sel' may affect it.

Reproduced from scratch, clean Cuda Qt5. There's nothing needed to config, just use clean Cuda and follow steps.
