Requirements and context
We have found the same issue and it caused multiple errors in the Magento 2 admin dashboard until we identified the JS error being caused by the new "Adobe Help Center" widget that was injected today for the first time.
I don't understand why Adobe did this.
I disagree with Adobe forcing this into our site without giving us a choice or opportunity to opt out before it started running.
And at this level how did Adobe push this new code into our site this morning without doing sufficient testing that it broke our admin screens so easily?!!
More importantly I completely object to Adobe having the ability to push code into our Magento 2 open source version, completely self hosted site.
What else are they doing or going to inject or force into our sites?!
Seriously, Adobe, WTF.
