BUG REPORT: SQL Editor selects too much text after you hit return and select "one line"

cursor-1.png shows three lines of text in SQL Editor, with the cursor positioned in the middle of the 1st line:

cursor-2.png shows the effect of pressing the Enter / Return key:

Up to this point, everything is as expected.

cursor-3.png shows the anomaly: after pressing Enter / Return, I then held "Shift" while pressing "cursor down" ONCE, to select the second line of text "efg". However, two lines of text were selected: "efg" and the first four characters from line 3. I know of no other application that behaves this way.

cursor-4.png shows what I expected to have happened after pressing "Shift" + "cursor down" ONCE:

Would you be able to make text selection behave as shown in cursor-4.png?
