SharePoint 2016 Server - mquery.js event deprecation
Stefan Goßner just checking in on this. Do you know if mquery.js has been updated to not use mutation events? (I'm running the deprecation/removal of mutation events, and the removal date is fast approaching.)
I received this communication below when I submitted support ticket to Microsoft concerning these depricated mutation events:
"I would like to inform you that the fix for this issue will be implemented on September 2024 CU for SharePoint SE. At the moment, there is no plan to implement it for SharePoint 2016\2019."
I didn't get any more info of the matter - like what are the business impacts etc. This much is certain, though: it does not look good 😞
Dave66_75 It's unfortunate they haven't given you what could be impacted. I think the patching model is now SaaS --> On-Premises. You could try doing some assessments on your own by installing an early release of Chrome and see if it breaks anything.
Mutation events will be removed from Chrome | Blog | Chrome for Developers
As an additional option:
You can also test by manually turning off mutation events. In Chrome, go to:
chrome://flags/#mutation-events
(you need to manually copy/paste that) and select "Disabled". That will require a restart.
It is too bad the older versions do not appear to be supported. Often, breakage from missing mutation events is quite subtle or not even noticeable. So it's possible the effect will be small when Chrome v127 is released.
If this won't get fixed on SharePoint 2016 / 2019, then a lot customers would no longer be able to work with it.
