I don't know where to find a field to attach a patch but it doesn't really matter, the fix is very simple.

> I found that the _startsWith_ method that can be found in the _utils_ module has unexpected behavior. It works well for most cases except when your pattern is repeated on or more times in your string :
> * string: foobar - pattern: foo -> true
> * string: foobarfoo - pattern: foo -> false
> It's because _string.lastIndexOf_ is use instead of _indexOf_.
