Currently when a user has a top toolbar enabled, the animation looks a bit odd. We should just do a cross fade in this case instead of doing "fade_in_up.xml"

can i work on this issue?
@ahmedmamdouh13 go for it ๐ please let me know if you run into any issues!
Thank you for the opportunity ๐
hey, i made a PR but I'm not familiar with TaskCluster.yml.
should i do something for the message appearing in the end of the PR?
Thank you!
Tested and verified, following the same steps as in the description, on Nightly build 200331 with Nokia 6 (Android 7.1.1), Xiaomi Mi Pad 2 (Android 5.1) and Samsung Galaxy Note 10 (Android 10).
@sblatz @ahmedmamdouh13 could you please take a look at the video and confirm that the animation for "Search or enter address" is the expected one? Thank you.

@sflorean yes.
