HtmlDocument.FromString problem

[BB <adamnt42@xxxxxxxxx>]

After recent Gambas updates (origin/master) I get the following error:

Parse error : Invalid tag !
 Line 79 , Column 14 :
  src="https://www.go

The full source page html line concerned is:

<script async 
src="https://www.googletagmanager.com/gtag/js?id=G-6QSTBX299S";></script>

Can anyone suggest what is going wrong?
