text y is NaN

[Tokubara]

When I export the SVG and open it in Inkscape, I notice that the text does not appear. However, when I open the same SVG in a browser, the text is visible, but its position is inconsistent.

Upon investigating, I found that the issue is caused by the y attribute being set to NaN in the <text> element, as shown below:

<text x="32.829978942871094" y="NaN" font-family="Segoe UI Emoji" font-size="20px" fill="#1e1e1e" text-anchor="middle" style="white-space: pre;" direction="ltr">1 2 3 4</text>
