Not working HTML5 Editor since 8.2

Hi,

since the update from servoy 8.1.4 to 8.2 we have problems with the html5 editor.
No form elements are displayed and can’t switch back to the standard editor.
It doesn’t matter if switching from the standard editor to the html5 editor or open a form with a webcomponent element and the form editor tries to open it with the html5 editor automatically.

Please advise.
Thanks

for others that also have this, do you switched the default port 8080 to something else?
So is the editor url that is generated and logged to the workspace log file when opening an editor an url with a port number that is not 8080?
It seems that we have a problem when that is not the case: https://support.servoy.com/browse/SVY-11550
