Merge https://chromium.googlesource.com/chromium/blink/+/adc5b8bec2d8c6a857b3c930ca7484f76cad1367 SelectorChecker::checkOne casts to StyledElement just to call classNames, but this method is on Element so there's no reason for this. The cast here also looks pretty suspect. The method also casts to HTMLFrameElementBase to call containsFullScreenElement which is also on Element so the cast can be removed.
