I have been using the booking widget for my client’s website and I am experiencing a bug in Safari.

Steps to recreate the issue:

1. Visit a page with the booking widget: https://coventry-accommodation.co.uk/properties/brownshill-green-3-bedroom-apartment/
2. Refresh the page

OS: macOS Big Sur 11.1
Safari Version 14.0.2 (16610.3.7.1.9)
