I saw something worth noting but easily worked around. I had a control (responsive grid) on the main form and the same control on a different form with the same name. When changing the size of the items in the responsive grid on the secondary form, those changes where immediately shown on the main form as well. Changing the name of the control on the secondary form fixed the issue, but the automatic naming convention for the HTML objects must be producing duplicate names.
How can this be reproduced? Do you have a test project?
I retested this here with controls with same name on main form and child form in the demo Demo\Basics\Multiform and I could not see an issue. Internally, the component name becomes FormNameComponentName
