Hello,

Thank you for the review.

Regarding those iframes, they are pure evil to handle in web-extension and it took me quite some time to make it work (more-less).

In the example you send (very nice example), the whole right down square (preview part) is already in iframe and scrolling there works.

The smaller squares inside it are nested iframes (iframes inside iframe) and seems like Firefox (and Chrome as well) is not injecting the web-extensions in nested iframes (so scrolling is not working there).

I will try to investigate this further and I can ask community about this as well.

This issue was so far not a priority since for a none-developer users this scenario is quite rare.

Thank you for pointing this out, I'll let you know what I find out.

Have a nice day.

Best regards,

Juraj Mäsiar
