(Keywords: parity-chrome)

At present, we have an OOP iframe vs. in-process iframe difference where the OOP side matches Chrome:

Our in-process case makes iframes in a designMode = "on" framer unfocusable while our OOP case and Chrome don't let designMode affect focusability.

Summary: Firefox make in-process iframe in designMode framer unfocusable → Firefox makes in-process iframe in designMode framer unfocusable

According to editing API WG, designMode is typically not used by new apps. So, I think this shouldn't have higher priority than P3.

Severity: -- → S3
Keywords: parity-chrome
Priority: -- → P3

Fission Future

Not a priority since this is a corner case plus we're now matching Chrome's behavior.
