What's Wrong?

When I open the left bar, it results covering the more left part of the dialogue panel

. I can not even read the left part of the prompts I am writing. Reducing the left bar size does not help, enlarging the app size helps, but only partially. Only solution is to close the left bar.

What Should Happen?

The panels of the app should resize automatically, when the left bar is opened.
