Status: NEW

In Bug 1607032 and Bug 1918202 we limited device orientation spoofs to primary results (based on our screen dimension spoofs) - there is no additional entropy as it's still based on our spoofed values - it was to make our spoof "spec compliant" and benign (non-paradoxical). Note that android uses a different angle value to desktops

This is similar to Bug 1885101 where we had to patch iframes to return the spoofed screen etc dimensions: i.e Match screen and window properties with top window.

Something similar is happening here - we're not adjusting the iframe's expected value based on our spoofs

• On desktop it always seems to report {"mozOrientation":"portrait-primary","orientation.angle":90,"orientation.type":"portrait-primary"} regardless of the iframe's dimensions

STR:

• control
  • disable RFP and have device on desktop in landscape mode
  • run PoC
  • everything should match e.g. {"mozOrientation":"landscape-primary","orientation.angle":0,"orientation.type":"landscape-primary"}
• enable RFP
  • make the window landscape (so RFP spoofs as landscape, which you already are)
  • run PoC
  • document (top window) is fine (landscape), but the three different sizes iframes all report portrait
