Summary:
Hi!

When I resize the debugger pane, the editor scrolls randomly, oftentimes scrolling the current selection out of view. 

This makes it hard to keep my bearings in a source file as I adjust panels.

Please see attached video.

Steps to Reproduce:
Select text in the editor
Resize the debugger panel

Expected Results:
Debugger panel resize. Text in the editor remains stable (i.e. the line of text at the top remains the line of text at the top)

Observed Results:
On mouse-down, the editor sometimes scrolls randomly, making me lose my position in the code and breaking my train of thought as I scroll to re-acquire my position.

Version:
Version 9.0 beta (9M136h)
10.12.5 (16F73)

Notes:


Configuration:
I use all-black for my code highlighting - source kit hasn't crashed :-).  Text with different colors reacts badly with the chromatic aberration in my eyeglasses, leading to migraine-level headaches).
