Subcircuit boxes don't render in `groups` environment

Describe the bug
When using subcircuits in a yquantgroup environment, the borders of the subcircuit box don't render.

To Reproduce

\begin{figure}[h]
	\centering
	\begin{tikzpicture}
		\begin{yquantgroup}
			\registers{
				qubit {} q[2];
			}
			\circuit{
				x q[0];
				cnot q[1] | q[0];
			}
			\equals
			\circuit{
				cnot q[1] | q[0];
				[this subcircuit box style={inner ysep=6pt, "Two $X$"}]
				subcircuit {
					qubit {} q[2];
					x q;
				} (-);
			}
		\end{yquantgroup}
	\end{tikzpicture}
\end{figure}

I also tried using a dashed style, which unfortunately doesn't seem to work either. Neither produces an error, it just won't render the borders.

Expected output
I would expect a solid-border subcircuit box around the two X gates.

Environment
Compiled using PdfLaTeX with yquant 0.6 and tikz v3.1.8b.

Once again, thank you for the project @projekter!

Thank you for reporting this. Within groups, the frameless attribute was applied via a normal style, not an argument. This did not get reset at all appropriate places.

Thank you for the quick fix!

On an unrelated sidenote, I was wondering if it was possible to make gates with dashed instead of solid borders?

Sure, just pass [dashed] as an attribute to the gate (or any line dashing pattern that TikZ understands). You can use arbitrary TikZ styles, as shown in the manual examples (have a look for example at pages 122 and 123 in the current master version).
Or, if you want to apply it to all gates of a certain type, add it to the respective style of the gate (e.g. \begin{yquant}[operators/every h/.append style={dashed}], or even globally in the document by using \yquantset{operators/every h.....}.
