Logic App (Standard) inline script window is too small

We have issues using the script editor for actions like "Execute JavaScript Code" since the editor window in the Azure portal is pretty small. As you can see on the screenshot the editor currently supports like a dozen lines and the hight of the window seems to be fixed, even so the side-menu that includs the editor has plenty of space.

It would be great to have the available space filled up so the editor window adjusts with the browser size. Should be possible pretty easy, right?

Thanks in advance,

Ruben
