Sidenotes do not avoid each other when called inside definition

[dwarfmaster]

Description

When adding two sidenotes too close to each other, kaobook manages to place them so that they avoid each other. However, if they are placed inside a definition, it seems the floating behaviour is disabled.

Minimal Working Example

\documentclass{kaobook}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{kaobiblio}
\usepackage[framed=true]{kaotheorems}
\usepackage{kaorefs}

\begin{document}
\begin{definition}
Some text\sidenote{Hello}\sidenote{World}
\end{definition}
\end{document}

Expected behavior:
I would expect Hello and World not to overlap.

Actual behavior:
Hello and World actually overlap.

Turns out it is linked to the mdframed environment, it works as expected with framed=false.

Yep, normally the sidenotes avoid each other because they are so-called "floating". However, we turn the floating off when they are inside other floating environments (such as figures and tables) or tcolorbox environments. There is some context in #39, however I think that issue dates back to the mdframed era, that is, before we moved to tcolorbox. We should indeed check whether the "floats lost" issue of #39 still occurs with tcolorbox..
