Too much empty space before a TikZ CD with a bent arrow with looseness

Question

As you can see in the following example, there is too much empty space between the text and the diagram when I use an arrow with bend left=100, looseness=2.

How can I avoid it?

\documentclass{article}
\usepackage{tikz-cd}
\usepackage{mwe}
\begin{document}
\blindtext As you can see, there is too much empty space here:
\[
\begin{tikzcd}
D\ar[r]\ar[dr, bend left=100, 
    looseness=2]&U\ar[dl]\\
C\ar[r] & K
\end{tikzcd}    
\]
\blindtext
\[
\begin{tikzcd}
D\ar[r]&U\ar[dl]\\
C\ar[r] & K
\end{tikzcd}    
\]
\blindtext
\end{document}

Answer 1

Once upon a time @marmot also know as @Schrödinger's cat wrote the interesting TikZ library bbox which solves most problems similar to yours. The library is no longer part of the TikZ bundle (consult marmotghost), but it is available on CTAN nonetheless.

Loading it you can write:

\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{bbox}
\usepackage{mwe}
\begin{document}
\blindtext 
As you can see, there is too much empty space here:
[
\begin{tikzcd}[bezier bounding box]
D\ar[r]\ar[dr, bend left=100,
    looseness=2]&U\ar[dl]\
C\ar[r] & K
\end{tikzcd}
]
\blindtext
\end{document}

and obtain the following result:
