The extension doesn’t work with elements in iframes. It shows a _“Could not read the required data from the element.”_ error message

Go to any CodePen-based demo such as https://codepen.io/bramus/pen/vYvXWyv and right click the iframe’s contents and select Inspect. The extension will show a _“Could not read the required data from the element.”_ error message:

Reproduce the issue using the linked CodePen demo, then inspect how the extension reads data when Inspect is used inside the iframe. Done means inspecting elements in CodePen-based iframe contents no longer shows the “Could not read the required data from the element.” error.
