Whenever i open a TeachingBubble, other component such as IconButton and Nav are affected as their :focus background gets set to the same blue as the TeachingBubble.
Behavior only appears once the TeachingBubble is triggered, and it affects all "button".
Other components have a blue background when focused.
Other components should not be affected by the TeachingBubble.
We just did the conversion to styles, appears that the :focus style added by the teaching bubble isn't scoped to the teaching bubble's button, therefore adds style to anything focusing on the page.

We just merged a change and are in progress of publishing a new patched version. Sorry for the bug! We area also adjusting our css tooling to avoid this category of problem completely.
