RH 2017 - Increasing the tri-pane's width in the HTML5 Responsive Layout is painful - How to fix it?

Hello Friendly RoboHelpers,

In RH 2017 (13.0.2.334) with a HTML5 Responsive layout, if you decrease the width of the tri-pane border by dragging it to the left (not collapsing it, but dragging it), it drags smoothly and quickly without any issue. But if you try to drag it to the right (to increase the size), you can only drag it a few pixels before the mouse stops dragging. This means to increase the width it requires, multiple minute painful drags (unless you very carefully and slowly drag the mouse to the right).

Here's a brief video that shows what I mean:

How can I fix this issue so that it's just as "snappy" dragging to the right as it is to the left? If you have RH 2020, do you see this same thing? 

Thanks in advance!
