As discovered in #9495 (comment), the fact that we allow the pre-publish checks to be turned off causes the editor bar to not fit on mobile (notably iPhone 5 size screens in german), where the width of the publish button label can say "Zur Überprüfung einreichen...".

Suggested solution: if a user disables the pre-publish checks, this only works on larger than mobile breakpoints, and on mobile, the pre-publish checks are always enabled. This is similar to how the "Unified Toolbar" function works: this is disabled on mobile because it technically isn't feasible to dock the toolbar to the top on mobile web due to how iphone treats fixed position.
