UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.86 Safari/537.36

Steps to reproduce the problem:

Able to reproduce the issue on latest Chrome stable and older stable versions as well i.e., 59.0.3071.86, 58.0.3029.110, 57.0.2987.133 on Windows 7, mac and Linux.
Status: Untriaged (was: Unconfirmed)
Labels: -Needs-Bisect -M-59 M-61
Able to reproduce this issue on Mac 10.12.5, Win-10 and Ubuntu 14.04 using chrome reported version #59.0.3071.86 and latest canary #61.0.3136.0.

This is a non-regression issue as it is observed from M51 old builds(as in attached "warning@M51.jpg"). 

Note: From M50 and older builds, the warning "<link rel=preload> must have a valid `as` value" is not seen" rather in place of that another warning is seen as in attached screen shot "warning@M50.jpg".

Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!

I am still observing the "<link rel=preload> must have a valid `as` value" in Chrome 73.
