Set max width for metabox #13268
Product owner: @thijsdevalk
We don't set a max width for the contents of our metabox, which means that sentences run longer than the ideal width we advise, and for instance on high resolution screens the marking icons in the analysis are crazy far away from the results they're supposed to mark.
Add a max-width of 800px to the metabox. That will make it roughly the same width as the default content width of TwentyNineteen and display everything in the way it was intended.
