When performing multi-line edits in the query editor using Alt+Mouse selection, you can select text across multi-lines however when you perform a copy, it only copies from the first line of text. When you then multi-line paste, it repeats the first value in each line.

To Reproduce

Steps to reproduce the behavior:

1. Go to Query Tool
2. Select several rows of text with multi-line selection (Alt+mouse), for example dates across rows, Cntrl+C to copy, arrow the cursor over and press Cntrl-V to paste.
3. See the error that the rows of text pasted are just the first line.

Alternatively, multi-select rows of text, Cntrl-C, switch to a different text editor and paste and see that only the first line of text was copied.

Expected behavior

If block selecting text and copying, the paste should also be block pasted.
