Add scroll bar to Create New Bulk Post

Currently, the blog editor doesn't scroll in its box, which means all of the formatting buttons get pushed off screen. This is especially difficult when adding images to the blog - you have to scroll all the way to the top of the web page to click the "add media" button, which takes you away from the place you're wanting to insert the image. It's a lot of unnecessary scrolling back and forth. Please add a scroll bar in the editor box so that you can scroll through the blog post while keeping the formatting buttons on screen.
