Meanwhile, is there a way in which all vendors can prevent their

This is not really. The preload scanner has no idea bout styles.
I think it's safe to say that, for the browser to load assets marked as
'display:none;' makes little sense
<script> elements are display:none, note.
So are <link> elements. Both get preloaded.
And people do in fact depend on display:none images being preloaded on
the web today. People paint those images to canvases, unhide them and
expect them to show immediately, etc.
