JavaScript mutation events deprecation in Chrome and Edge and impact on SharePoint Server

In the last couple of months we received questions from several customer regarding the JavaScript mutation events deprecation/removal from Chrome and Edge Browsers as discussed in the following articles:


Users of SharePoint might have noticed a warning similar to the following in the Console of affected browsers:


July 2024 CU for SharePoint Server Subscription Edition Microsoft which was just released includes an update which addresses this issue:

Be aware that there is no currently no plan to release a fix for this issue for SharePoint Server 2016 and SharePoint Server 2019 as these products are in extended support and this issue doesn’t block the product functionality.


  1. Will this change also affect Microsoft Edge?


  2. Hi,

    if “this issue doesn’t block the product functionality.” do you have an example what won’t work in the future?
    Or does this just affect own Solutions.

    Kind Regards
