imported/w3c/web-platform-tests/css/css-animations/Document-getAnimations.tentative.html is now failing, but that's most likely because it worked by pure magic before. Hopefully this will be an easy fix, looking into that now.

Use uint64_t. Hopefully we'll never have that many animations.

If we created one animation every nanosecond, which is a bit of stretch since we need at least a few CPU cycles to create & destroy one in the main thread, it takes like ~584 years (2^64/(10^9*3600*24*365.24)) to overflow a 64 bit unsigned integer. We can safely say an issue that arises after such a runtime horizon is outside the scope of the WebKit project.
