**Description:**
liftOnScroll not working properly when having EditText with minLines/minHeight attr. as one of children in scrolling view

View is scrolled along with edittext that keep expanding to the next line. But liftOnScroll elevation still not shown until reach minLines/minHeight attrs.

Try playaround with sample code and see elevation on toolbar when typing in edittext.

**Expected behavior:** liftOnScroll elevation should be shown correctly.

Start by running the attached appbarlayout-elevation.zip sample on the listed Android environments and reproduce the behavior while typing in the EditText. Read the Material Components Android implementation around AppBarLayout and liftOnScroll, then verify that toolbar elevation appears while the field expands rather than only after reaching its minLines or minHeight.
