IE8 behavior (correct)

Scenario:
Multi-row textarea element (paragraph style text input box).
Populated with multiple lines of text.

Actions to reproduce:
Highlight a line of text in the middle of the paragraph, and drag cursor outside of text input box boundary (either left or right).

Desired outcome (Firefox, IE8 behavior):
Highlight stops (vertically) at the Y position of your mouse cursor, outside of the textarea boundaries.

Webkit behaviour:
Highlights entire text box from the initial line to the beginning (if exited left) or the end (if exited right), regardless of where your mouse cursor is vertically.

Attached 3 images to illustrate for comparison (Firefox, IE8 and Chrome behaviors)
