Description Anne van Kesteren 2023-04-01 03:05:57 PDT 
It seems that we currently don't throw in places that are not supposed to take shared memory: https://wpt.fyi/results/xhr/send-data-sharedarraybuffer.any.html.

Per https://github.com/WebKit/WebKit/commit/02a7ddd1949f734535c90d93a6d10eea06afcdce#diff-93b28dd1c69f1ae018f811d9fa195b7ccff18e02ffca56c1864ba79ebbe56b30 we have at least some support for [AllowShared], so why does the IDL layer not end up throwing here?

Yusuke, do you know?

I have no idea, probably XHR is not using AllowShared.

It is probably largely depending on how XHR is implementing send function, I guess.
