When saving thumbnail "use current frame" doesn't work if casting [#17469]

When saving thumbnail "use current frame" doesn't work if casting, like to ChromeCast. Just get a black image.

If it can't be done, then MMW5 should refuse to save the black image, or should preferably grey out the option.
