1773499 - Re-use the result from JavaScript validator

Status: NEW

Description

[Andreas Farre [:farre]]

In Bug 1532644 we plan to implement a JS Oracle to be able to block no-cors cross-origin responses that poses as JavaScript but isn't.

In the case where the validator finds that the resource is JavaScript, it would be nice to re-use that result and not need to double parse.

Isn't the plan for bug 1532644 to only validate the first 1024 bytes? Reusing a partial parse seems finicky and not necessarily worthwhile.
