Youtube component: Handle videos with no maxresdefault thumbnail #5525
Description
Hello. If I enable Show Preview when using the Youtube component, seems it uses the maxresdefault thumbnail. Some videos like this don't have thumbnails of that size, which results in the alt text being shown. You can check available thumbnail sizes at https://youtube-thumbnail-grabber.com/. Thought this was a bug at first, so not the most intuitive UX.
When trying to use that video, I checked the console logs and found the url below being logged. I'm guessing this is requesting the image and optimizing it?

In such cases, maybe WebStudio should try using other thumbnail sizes that don't return a 404 (sddefault.jpg is the next highest resolution), or show the user some info about this?
