Customizer not clear that Collapse requires Component animations

[dagobert]

I have customized the bootstrap download to include "panel" and "collapsible". The resulting CSS file is missing at least two rules to make collapsible work:

.collapse {
display: none;
}
.collapse.in {
display: block;
}

Here is my customization link:

@dagobert I'd first mention that per the documentation, collapse requires the transition JS which means you also need the Component animations (for JS) LESS attribute checked.

Here is a corrected config.json file.
