Yes, the CODE editor cannot handle that, RSE's LPEX can.
BTW, another behavior that has always been a little irritating - let's say that I have selected a few lines by dragging down while the cursor is at the start of the lines. If I click on the line immediately below the selection, and at the beginning of the line, before the first character but not in the sequence number area, it does not deselect - I need to click somewhere else.
If the last line of the block is selected in its entirety, then most probably the cursor blinking at the start of the line that follows is actually the end point of the stream selection (you may verify this by entering, on the LPEX command line: block.bottomElement)... Now clicking on that particular point (or even inside the SEU prefix area of that line) won't clear the selection.
