WindChill extension - Mashup style problem

Hello everyone,

I have a problem that exists only when the WindChill extension for Thingworx is installed.

If you put a Fieldset in a responsive layout (no matter if it is in a header or in a column), it will always display scrollbars in the container, which is quite annoying.

I tried to find the piece of code responsible of that in the extension but I did not manage to find it. I also could not find any workaround for this issue.

Does anyone found a way to fix this ?

Thank you very much !
