HTML import filter very (too) basic

[Jens Tröger]

If I had to take a guess then I’d say that the problem shown in the initial image is caused by the CSS class resolution. The HTML div is there (see the grey border) but it looks like the CSS of the div does not propagate correctly.

I’ll file a bug, but if I had to fix it I’d start digging around in that CSS resolution for nested elements (both, div and span)… 🤓

Cheers,
Jens
