Lethal Tempo page:

"When first released on the PBE, only Lethal Tempo's bonus was supposed to exceed the cap. However, the effect disabled the cap instead. This was stated to be a bug and was fixed, but at some point the fix was reverted. It is unknown if the revert was intentional, but at present there is no cap on attack speed while Lethal Tempo is active."

I found this Riot tweet about a Lethal Tempo bug, but I don't think it's the same one: https://twitter.com/RiotWrekz/status/913464887287803904

Riot Wrekz: "Lethal Tempo - Fixed a bug causing this to always break the AS cap instead of only while Lethal Tempo’s bonus was active."
