Steps to reproduce the problem:
1. Use Android N (I used Nexus 10 with custom rom for Nougat 7.1.1, but it can also be reproduced on qemu with Nougat 7.1.1)
2. ./out/Release/bin/run_chrome_public_test_apk -f org.chromium.chrome.browser.ItemChooserDialogTest#testUpdateItemWithIconToNoIcon 

What is the expected behavior?
Test to pass

What went wrong?
Test failed with error:
