Subject: [PATCH] Merged in feature/SW-1736-foating-booking-widget (pull
 request #1696)

Feature/SW-1736 floating booking widget

* feature: Add floating booking widget on start page SW-1736

* fix: Make sure we don't try to use IntersectionObserver on the server

* fix: make sure that we disconnect the intersectionobserver when dismounting

* fix: pass searchparams to floating bookingwidget
