Preamble
If you have the patrol user right you get a "Mark as patrolled" link in various parts of the user interface (in diffs and watchlist). This is currently a confirmation-less link that will mark as patrolled a specific edit.
Problem
It's a bit too easy to accidentally click this link. It can happen particularly for users on touchscreen devices.
Possible solutions
1: Allow users to prevent/disable the patrol script?
Some users may want to simply prevent/disable that specific script and follow the normal link which shows a form to be submitted. The form already exists and it's the one accessible to users with JavaScript unavailable/disabled.
As workaround actually some users may want to create a snippet like this that should be run after the mediawiki.page.patrol.ajax ResourceLoader module:
$( '.patrollink[data-mw="interface"] a' ).off( 'click' );
2: Ask for confirmation?
Some users may want to see a confirmation before running the action.
3: what else?
