It's bad that "x" isn't showing in landscape, but it affects only landscape in "this" orientation. Easy workaround if you rotate device by 180 degrees (still landscape), the notch is on the other side and the "x" is visible.

Hey lod@ are you making some progress on this issue?

Yes, close to done but I'm at a summit today/yesterday and was traveling tuesday. Hoping to get the CL out by tomorrow.

Use autolayout and safearealayoutguide for form input accessory view.

Rewrite the view to use autolayout in order to use safearealayoutguide
for iPhone X compatibility.
While writing this CL I identified a lot of dead code here which should
be removed in a future CL: the entire use of left and right frames for
split keyboard applies only for iPads running on iOS < 9, which aren't
supported. I will do a follow up CL removing it.

Reland Use autolayout and safearealayoutguide for form input accessory view.

Initialisation of view after adding to parent view resulted in
the view not having accessibility labels correctly set on iOS 9.
An alternative fix was to call "setNeedsLayout" after initialisation.

Autofill keyboard accessory respects the safe area.
