Just tried dragging some fields into a two column row placed inside the form in order to have two fields sit side by side. That didn’t work because when you try dragging a field it grabs the whole form. Then I did it through the inspector which does work, but then the builder became unresponsive.
Found a lot of these in the console:
Suppressing inaccessible window.event undefined TypeError: can't access dead object
