-----------
[Site Isolation] Cross-site iframes nested within same-site iframes cannot
receive mouse events
https://bugs.webkit.org/show_bug.cgi?id=279398
rdar://135438488
Reviewed by Alex Christensen.
The `passMouseXEventToSubframe()` function is used to send mouse events to
local iframes, but it may
later hit test an out-of-process iframe. In such cases, the function must
return a
`HandleUserInputEventResult` so we can tell the UI process to forward the event.
