Log Message:
-----------
[Site Isolation] AutofillLoginCredentials is broken when the focused element
is inside a cross-origin iframe on iOS
https://bugs.webkit.org/show_bug.cgi?id=310075
rdar://172718686
Reviewed by Alex Christensen.
autofillLoginCredentials() sends the AutofillLoginCredentials IPC message
to m_legacyMainFrameProcess, which is the wrong process when the focused
element lives in a site-isolated cross-origin iframe. This breaks
autofill credential selection for login forms in embedded cross-origin
iframes — a very common pattern for payment and authentication flows.
Pass the focused element's frame identifier through to
sendToProcessContainingFrame(), matching the pattern already used by
SetFocusedElementValue, SetFocusedElementSelectedIndex, and
SetSelectElementIsOpen.
