Hermione capture screenshots of elements in iframe incorrectly

The problem is, that when you try to capture an element in iframe with hermione#assertView the element coordinates doesn’t consider iframe position.

See tests/iframe.hermione.js.

Setup

npm install

Reproduce

Capture screenshot of element in iframe when iframe is at 0,0 on page:

GRID_URL=http://localhost:4444 npm run nooffset

• page preview
• hermione report

Capture screenshot of element in frame when iframe is shifted down:

GRID_URL=http://localhost:4444 npm run offset

• page preview
• hermione report
