        <pre>The warnings are unrelated.

Definitively, the problem is triggered by the JS from modernizr.

Try:

1) Render white
HOME=$(mktemp -d) Tools/Scripts/run-minibrowser --gtk --enable-write-console-messages-to-stdout=true <a href="https://people.igalia.com/clopez/wkbug/173768/midori/m1.html">https://people.igalia.com/clopez/wkbug/173768/midori/m1.html</a>


2) Render ok
HOME=$(mktemp -d) Tools/Scripts/run-minibrowser --gtk --enable-write-console-messages-to-stdout=true <a href="https://people.igalia.com/clopez/wkbug/173768/midori/m2.html">https://people.igalia.com/clopez/wkbug/173768/midori/m2.html</a>



And the only difference is:

$ diff -u <(curl -s <a href="https://people.igalia.com/clopez/wkbug/173768/midori/m1.html">https://people.igalia.com/clopez/wkbug/173768/midori/m1.html</a>) <(curl -s <a href="https://people.igalia.com/clopez/wkbug/173768/midori/m2.html">https://people.igalia.com/clopez/wkbug/173768/midori/m2.html</a>)
