Bug 1934589: propagate line- and column-numbers to "securitypolicyviolation" events triggered by `javascript:" URL navigations. r=tschuster,smaug
The column number of a violation is not specified [1], [2]. It could for
instance for `v = createViolation` be 0, 1, 4 or 5.
Hence not adding tests for this. In any case, a non-fixed value might be
more helpful than "1" which was used before this patch.
For line numbers, the desired value is more obvious, but unspecfied too
[3]. Here, Chrome's behavior, which is one-based, is matched.
