Lbry-desktop: Pause gifs in thumbnails on first frame until hover

Example of an animated gif (NSFW sorry): lbry://@15secondstofap#8 thumbnail

Resolving the claim shows that the thumbnail URL doesn't include a .gif extension. It looks like a directory URL. So i'm not sure how it's even getting the gif from there. But I suspect this is why the app isn't turning off the animation.

Thanks for filing! I think we only fixed this on claim previews to prevent it happening on a whole bunch of claims on a single view. I think animating on these pages is okay.

This one animates when you see it in trending, which is how I noticed it. Is that what you mean by claim previews?

Yes, I thought you meant it did on the channel page. Yes, then it could be related to a channel preview or the lack of a gif extension as you mentioned. Nice catch!
