Pane re-sizing allows you to shrink but not expand

I'm not sure if this is the same issue or not but I'll just put it here since it is similar. When I start with a small window, select a new challenge, and then try to resize, then the editor pane stays small. The width of the editor pane seems to always stay the same width as it was when the challenge was initially selected.

Also, on small window sizes, the error messages in the bottom right are hard to see. See gif for demonstration.

@mstellaluna and @beaucarnes, I'm working on this now. Made some changes to both the editor and the output so that they expand and shrink horizontally when the browser window is resized. I'm currently working on a way to resize them vertically, and also resize horizontally/vertically when the panes resized, but the window size remains the same.
