Shot in the dark from https://github.com/brave/brave-core/compare/fix-google-drive-autoplay-bj But I could be wrong. But something like this?

constexpr char kSlideshare[] = "https://[*.]slideshare.net/*";
constexpr char kSlidesharecdn[] = "https://[*.]slidesharecdn.com/*";
[...]
{ ContentSettingsPattern::FromString(kSlideshare), ContentSettingsPattern::FromString(kSlidesharecdn)}, { ContentSettingsPattern::FromString(kSlidesharecdn), ContentSettingsPattern::FromString(kSlideshare) },

I see this in the logs

Uncaught DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.

I think the better solution here is #8514, which would be a good, systematic level fix

That being said, once brave/brave-core#5433 lands, i'd be a-ok adding these exceptions in, but would like to mark them for removal once #8514 lands

This is now working, closing ticket.
