Input Accessory View Broken with Multi Window

I'm seeing very strange behavior with the input accessory view in multi window on iPad in iOS 13. The first view that gets created in a new window receives its input accessory view normally, but all future views in that window do not. Despite calling reloadInputViews, the views never seem to request their accessoryInputView and the accessoryInputView is never added to the text input window. As a result - input accessory views seem to be pretty broken in multi window on iPad in iOS 13. I'm wondering if anyone else has seen this or knows of a workaround?
