Print stylesheet unexpectedly gets onload attribute

[swissspidy]

If I understand #444 / 07be40b correctly, print stylesheets should be unaffected by the script. And that seems to actually be the case—the print stylesheet is not part of the extracted critical CSS.

However, the <link> tag still erroneously gets an onload attribute, which does not make sense.

Input HTML:

<link rel="stylesheet" href="css/print.css" media="print">

Expected output:

(unchanged)

Actual output:

<link rel="stylesheet" href="css/print.css" media="print" onload="this.media='print'">

Thanks for the issue 😊
I'll try to find some time to look into this in the next days.

Moved this issue to inline-critical because it's responsible for the inlining & rewriting.
Keeping this open until the issue is fixed upstream.

Should be fixed in v6.0.2
