Am I correct in assuming that in this case, the documentation is wrong? What is the process to correct this?
This update of the help pages may give an estimate (25 August 2009) on when the feature was initially implemented: https://en.wikipedia.org/w/index.php?diff=next&oldid=309966422
I believe that this change added behaviour that runs counter to the documentation in https://meta.wikimedia.org/wiki/Help:Displaying_a_formula#Rendering
I believe that this change may be the source of the bug: https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/Math/+/292952/
Thank You for the prompt reply!
