''k''(''x'') = −(''γ'' + ∇''f'')
The s above are there for a reason. And a minus sign is not the same character as a hyphen. In a Wikipedia article I saw a line break just after this minus sign before the left parenthesis. Are there any standards by which that is not an incorrect way to write something?
The problem occurs in Wikipedia's article titled "Bailout embedding". See in particular this edit: https://en.wikipedia.org/w/index.php?title=Bailout_embedding&diff=911126129&oldid=910966282
just after the words "with a choice of". As I altered the window geometry in Google Chrome, I could make the problem occur or not.
