I dread the day this plugin becomes deprecated and obsolete. The site I administrate is completely incompatible with Gutenberg, and I almost nuked a page on my site when I tried to use it. Thankfully I”m paranoid as hell, and I back my site up every time I make a change of any kind.
Problem solved. A friend of mine pointed this out as soon as I posted. I had images in there that were too big, and made the slider too big, causing the blue bar.
