[HTML] occlude={[refs]} not occluding when passing array of refs

[Remi-Tribia]

Hi,

I'm trying to ignore Html occlusion for transparent object, so I traverse my scene, and only collect meshes with material that has transparent=false in a ref array [{current: objA}, {current: objB}, ...] and I pass this array to the Html occlude prop.
Setting some breakpoint in the Html.js file, I can see the raytraceTarget seems correct (I get an array of Meshes) and is correctly passed to the isObjectVisible() method. But the Html elements are always visible, as if there was no occlusion at all (it works correctly just setting occlude={true}).
I'm using the latest version of drei (9.93.0), I also tried using "blending" but the Html element doesn't appear correctly (except behind transparent material suprisingly).
I guess I'm doing something wrong, or even what I want to achieve is not possible at all, seeing by default it's just the whole Scene that is used, I guess if one of my transparent object is parented to an opaque object, it will occlude anyway... But I would expect it to behave the same way as occlude={true}?

Thanks in advance!
