Using bootstrap in frames

Good day,

I just bought TMS Web Core and I am making small examples to see if I could make a web application showing the functionality I need.

I just found a problem I don't know how to solve it: I have a form containing a button and a frame also containing a button. Then I select Bootstrap and enter .btn-primary as the element class name for both buttons. When I run the test, I only see the button placed directly on the form having the bootstrap layout. The button placed on the form through a frame does not change.

How to make sure both buttons adapt to the bootstrap setting?

Was due to '.' in front of CSS classname.
We have fixed this. Next update will address this.
