<img . decoding="async" .> bug on JDK/JFX19 (MacOS) WebView/WebEngine

[Jerry Kramskoy]

Hi Guys,

 
Any <img … decoding=”async” …> does not get rendered on JDK/JFX19 (MacOS) WebView/WebEngine

 
Works fine on Windows 10.

 
This shows up with WordPress 6.1 up, whose default is to using async decoding to speed up Web page loading.

This can be disabled via a WordPress API call, but this then penalises SEO scoring.

 
Are you aware of this?   I’m guessing the ECMAScript engine that ships with MacOS version of WebView/WebEngine doesn’t support async.

 
It doesn’t show up in browsers on MacOS (11 …)

 
I’ve attached a standalone html file that demonstrates the problem.  If the ‘decoding=”async” is edited out, all works.

 
Thanks, Jerry Kramskoy
