Close address search on Esc press

[warm-coolguy]

I've noticed a few times that I tried to close the AddressSearch by pressing Esc. We should probably implement it for users expecting this.

• Don't forget Fullscreen Mode and other Esc interactions on implementation.
  • Suggestion: Use event and stop propagation/default if usable, else propagate.

Alternative solution: Make the X button on the search input accessible to keyboards.
