Hello!
I'm using percySnapshot() function from the @percy/puppeteer package to create snapshots in the test scripts. Pages with iframe page that contains map, e.g. from Google or Mapbox API, seem to hang indefinitely and so the percy build is never finalized. There's no error in the terminal. I look through the code, and the issue seems to be specifically on the second page.evaluate call in percySnapshot()?

I have isolated the general page and test setup in this repo (map api key is omitted). when running npm run percy, the first snapshot for index.html is taken successfully. The second snapshot for iframe_test.html hangs.
