Footnoterule fails in floating environment such as tcolorboxes

The current footnote rule adds the vertical line separator above the footnote content.
However, this causes problems in floating environments in which the "bottom" of the page is defined within the env itself, resulting in:

We can fix this by identifying the environments affected by this (might just be the tcolorbox env) and override the footnote rule for the specific env using %\AtBeginEnvironment {tcolorbox}{\renewcommand\footnoterule{}}.

• Check which common env's are affected
• Add overrides to template for effected env's
