Leaflet map preventing browser scroll

Question

Whenever the mouse pointer is hovering over a leaflet map, the browser does not scroll up or down. This happens even when I affix minZoom and maxZoom to an equal value. Is there a solution to this?

php.poverty.map.2009 <-
leaflet(options = leafletOptions(minZoom = 12, maxZoom = 12)) %>%
addProviderTiles("CartoDB.Positron") %>%
addPolygons(data = php.df.polygon.2009, 
          fillColor = ~php.pal.2009(percent), 
          color = "#b2aeae", # must use hex colors
          fillOpacity = 0.7, 
          weight = 0.3, 
          smoothFactor = 0.2,
          popup = php.popup.2009) %>%
addLegend(pal = php.pal.2009, 
        values = php.df.polygon.2009$percent, 
        position = "bottomright", 
        title = "Percent of Households <br> Living below Poverty <br> (Census, 2009)",
        labFormat = labelFormat(suffix = "%"))
php.poverty.map.2009

Answer 1

In my second attempt at answering this question I came across the leaflet.extras package which implements a selection of leaflet plugins in R. One of these is the Leaflet.Sleep plugin which can be implemented by adding the suspendScroll() function to your leaflet map in R.

Basic Example

First, install leaflet.extras using devtools::install_github('bhaskarvk/leaflet.extras').

library(leaflet)
library(leaflet.extras)

leaflet() %>%
    addProviderTiles("CartoDB.Positron") %>%
    suspendScroll()

See this page for an example.
