How to collect sub frame's statistics with 'about:blank' src?

When I load the url: fingerprintjs, I don't think I got the correct statistics. This page has a sub frame with src as 'about:blank', HTMLElement.offsetWidth and HTMLElement.offsetHeight are called in this sub frame, but I can't find those calls in the database. Sub frame is generated by javascript file in this web page. My fingerprinting.json is:
[
"HTMLIFrameElement",
"Date",
"AudioParam",
"DynamicsCompressorNode",
"OscillatorNode",
"MediaQueryList",
"CanvasRenderingContext2D",
"HTMLCanvasElement",
{"HTMLElement": {
"propertiesToInstrument": ["offsetWidth", "offsetHeight", "textContent", "appendChild"]
}}
]
How can I collect the correct information under such circumstances?
