      Description

      QML JS RegExp with lookbehinds (positive and negative) doesn't work as expected.

      example:

              // positive lookahead test
              const plaMatch = /foo(?=bar)/g.exec('foobar foobaz');
              console.assert(plaMatch != null, "Positive lookahead failed!") // PASS
      
              // negative lookahead test
              const nlaMatch = /foo(?!bar)/g.exec('foobar foobaz');
              console.assert(nlaMatch != null, "Negative lookahead failed!") // PASS
      
              // positive lookbehind test
              const plbMatch = /(?<=foo)bar/g.exec('foobar fuubar');
              console.assert(plbMatch != null, "Positive lookbehind failed!") // FAILED!
      
              // negative lookbehind test
              const nlbMatch = /(?<!foo)bar/g.exec('foobar fuubar');
              console.assert(nlbMatch != null, "Negative lookbehind failed!") // FAILED!
