Comment (by GDragoN):

 I have updated few live websites, but I installed Classic Widgets on all
 of them, I do not really see the need to use the new Widgets Panel on live
 websites or to experiment on the live websites with something that is
 clearly not needed right now. I have development setups for this very
 reason.

 I tested with no browser extensions, no must-use scripts that can affect
 this. On most websites, I updated it works, but on some that are broken, I
 see no way to fix it. Because this is so far a very specific issue that no
 one else reported or encountered, I am willing to accept that something
 very obscure is causing the problem, but I hope that there will be some
 changes in the code to validate the data before it gets used.

 The errors I have seen point to the problem with invalid data, so nothing
 is validating the data before it is sent. If that is fixed, I am sure
 similar issue will be avoided in the future.
