If link previews (e.g. to videos) are going to be marked "sensitive" when there's a CW, rather than just being hidden until the CW is opened, then there ought to be a way to undo that default the way there is for attached images.
Also, why doesn't Masto's HTML support/allow the <detail> and <summary> tags? That would be very helpful for selective hiding of content. #softwareGripe
@noiob I guess this is one of Masto's remaining big weaknesses.
