Are :has() CSS pseudo-selectors supported in Joplin?

[chentao]

I try to add some style to a specific <table> element. For that, I preceded that table by a <span>, hoping the following would work :

<span id="test"></span>
|AAA|BBB|
|---|---|
|ccc|ddd|

<style>
p:has(span#test) + table {
    background-color: blue;
}
</style>

But it doesn't work. IMO, it's because Joplin doesn't support the :has() pseudo-selector. Can someone confirm this ?

It won't work in Joplin 2.11 because the Electron backend isn't new enough, but if you try it on the 2.12 pre-release with newer Electron you might find more success.

Thanks.
I am using the flatpak version of Joplin, so I'll wait until it's been upgraded to 2.12 to test again.
