A follow-up patch <https://gerrit.wikimedia.org/r/#/c/231437/> which
increases the limit to 2,500 was merged; this means the character limit
will be 2,500 characters instead of 300 characters when it goes into
production next week. I expect that this limit will be reset back to 300
within a few weeks. Please see the associated Phabricator task
<https://phabricator.wikimedia.org/T107947> for more information.
