Can you add a test in Test_tableLinkForExpression please? but to be honest: i dont understand it; the URL seems valid on its own ( not in a html context ); is this maybe an issue of whatever renders the notification in the end?

[MichaHoffmann]

Ah i understand now; spaces are encoded as + by the stdlib (golang/go#4013) and the html/template package then escapes that again to &#43. I wonder wouldnt it be easier to not render the URL as html but just use "text/template"? That way we are sure we are not replacing anything else too.
