Uncaught Error: unsupported number: NaN when converting html with font-size:medium

[Zkamoth]

This error raise when I try to convert HTML like this one:

<div>
	<p style="text-align:center"><span><span style="font-size:medium"><strong>TEXTO DE PRUEBA</strong></span></span></p>
</div>

PDFMake throws an error Uncaught Error: unsupported number: NaN because the component translate style="font-size:medium" to "fontSize":"medium" and PDFMake waits for a number.

Indeed, medium is not a supported keyword. Please, use a number instead (like 14px)
