Task Comments window sizing

When editing a task, the task comments tab resizes unproductively. When you expand/contract the task window size the areas in which you can read the comments are TBH, lame in terms of sizing and resizing. For example, if you make the task window larger, you don't gain any extra lines on the Comment list and the comment that is on the side doesn't resize nor is the divider between the two adjustable.

Can we get the vertical sidebar adjustable?
