**Description:** When running the demo 'components' app and when including it in my own app, the 'Mobile date input picker' does not look up to spec. In particular: - there is a large space between to input text box and the ok/cancel buttons - there is no hint to help with the expected input format the space appears to be due to the height of the 'Mobile calendar picker' which is also inflated (but hidden behind the input view)   **Expected behavior:** - there shouldn't be a large space between the input box and the ok/cancel buttons - there should be a hint to guide the input format see 'Mobile date input picker' https://material.io/components/pickers/#mobile-pickers  **Android API version:** 29 **Material Library version:** 1.2.0-alpha04 **Device:** Samsung S9 Emulator x86 (Nexus 5X)
