App crashes because of changing a shared Drawable on the fly. I found
out it is the SearchBar. It only happens on Android and in large apps
with lots of screens. Unfortunately I can't reproduce it in the
TestSuite. But by reading the docs of Android this crash is common and
caused by changing a Drawable which is still referenced. With a custom
SearchBarHandler the issues is resolved.

### Description of Change
