[whatwg] Iframe IDL sandbox readonly attribute

[Marta Pawlowska]

Hello Boris,
Thank you very much for your answer. I did noticed PushForward and this was
my suspect. However it is hard for me to understand why to use readonly in
that case?  Do you know any place/list/ling where such a concept "readonly +
PutForwards" is described? 

Best regards,
Marta

Note the PutForwards bit.

Yes, because of the PutForwards.

Though note that at least Gecko implements this as a writable DOMString 
for now, because of the issues I raised in the mail you cite.
