ignoreUrls may not work if top-most frame is `eval` or `anonymous`

ignoreUrls sometimes only looks at the top-most frame URL to decide whether to reject the error. But some frames have has no “source” and so they leak through.

Example:

SyntaxError: missing ) after argument list
  at new Function(<anonymous>)
  at Function._.template(/libs.js:123:1)
  at initializeTemplates(/app.js:456:2)
  at HTMLDocument.<anonymous>(/app.js:789:3)

Not sure what the solution is here. I’m not sure we should tear through and look at every frame (probably slow, e.g. m frames x n regexes).

Let’s just say I’m sensitive to this issue because I may have once deployed an inefficient regex into production that crashed browsers on certain inputs.
