User can't zoom in the page regularly, only map zoom is allowed
User can zoom the page, for example by zooming to popup or search box.
Try zooming to elements, for example
click on map to open popup
try zooming to the popup
Happens on iOS 13 Safari
User can zoom to elements instead of zooming the map. This will make the page scrollable and break zooming of map. This happens at least on the index page.
Situation is sometimes fixed by zooming out fully but not always. Sometimes page reload is needed to be able to move/zoom map again.
It might be difficult or impossible to disallow zoom entirely since zooming should already be disabled and Safari seems to ignore that.
