Stabilizing the blogger Post Settings panel

If you have a blog on blogger.com, you might have recently experienced an annoying problem. The right panel, with settings such as Labels only fully appears when you move the cursor into that area.

While trying to type in labels, it kept sliding most of the way closed, and I had to keep moving the cursor.

I finally discovered that if I click in the Labels area after clicking the button, that the panel would remain open until I moved back to the main part of the blog.
