[webkit-dev] Request for position on Event Timing

[Rob Buis]

I was not aware of Long Tasks API. However it seems to have a slightly 
different focus (task vs. input events). Also I am mostly interested in 
First Input Delay, and it was decided some time ago to not put it in 
Long Tasks API (see 
https://docs.google.com/document/d/1bYMLTkjcyOZR5Jt3vrulzMSoS32zOFtwyH33f6hW_C8/edit#).

Regards,

Rob.
