Failed to rendering a text in nested SVG

I wrote are two SVGs and I nested those and I got a blank image unexpectedly.

Is this a bug...? (Sorry. I can't classify that problem as bug, unimplemented feature, undefined behaviour or something else, because I'm not an expert of SVG specification.)

Version: 0.41.0
OS: Windows 11 23H2 22631.3447 (x86_64) and Arch Linux.

I got a same results in --use-fonts-dir option.

Text containing SVG (child.svg)

Works expectedly if this file only.
This file just needs to contain a text element.
But I wrote some elements and attributes for visiblity.

Note: I choose a Noto Sans but this problem is occured too in any system fonts.

<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg" width="100px" height="100px">
	<rect x="25" y="25" width="25" height="25" fill="red" />
	<text
		x="50" y="50" dominant-baseline="middle" text-anchor="middle"
		font-size="25" font-family="Noto Sans"
		fill="black"
	>
		Hello
	</text>
</svg>

Rendered Image (child.svg):

resvg child.svg child.png

Parent SVG (parent.svg)

<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg" width="100px" height="100px">
	<image x="0" y="0" width="100" height="100" href="child.svg" />
</svg>

Rendered Image (parent.svg):

resvg parent.svg parent.png

Actually behaviour (parent.svg)

and I got warning:

Warning (in usvg::text::layout:1115): No match for '"Noto Sans"' font-family.

Expected behaviour (parent.svg)

Completly same as child.svg in this case.

Reproduce the issue with the provided child.svg and parent.svg files, then inspect nested SVG image handling and font resolution. The fix is complete when rendering parent.svg produces the same visible text as child.svg without the missing-font warning.
