Scalebar not removed properly in v2.0.0 #538
Description
Hi again,
I've found an error related to methods.removeScaleBar, specifically this line
It seems that this.currentScaleBar.removeFrom(this) is no longer valid. Reproducible example below.
library(leaflet)
options(viewer = NULL)
leaflet() %>%
addTiles() %>%
addScaleBar() %>%
addScaleBar() %>%
addPolygons(data = gadmCHE)which produces the following output (polygons not rendered after error is encountered):
Same error message appears with
leaflet() %>%
addTiles() %>%
addScaleBar() %>%
removeScaleBar()this.currentScaleBar.remove() seems to work when in scope of function in browser console.
