Fail to set a boolean attribute

[kingyue737]

Source

[sample](https://pdfobject.com/pdf/sample.pdf){download}

Expected

<a src="https://pdfobject.com/pdf/sample.pdf" download>sample</a>

Actual

<a src="https://pdfobject.com/pdf/sample.pdf" download="true">sample</a>

This download="true" overrides the filename unexpectedly.

Reproduction

I want to reproduce it in online playground mentioned in README but failed, the stackblitz crashed once the dev server started

I'm on Windows using Edge 136.0.3240.64
