Marker with same ID results into broken html

Describe the bug When we create one single Icon for a Marker. And pass it to multiple Markers, the map would not display any markers at all. All icons need to have unique ID's. That means for each marker I need to recreate a unique icon, even if its the same symbol.

Is it not possible to create one icon and pass it to every marker?

To Reproduce

def create_folium_object(
    row: pd.Series, geometry_column: str, args: dict, geom_type: str
):
    if geom_type == "Point":
        args = copy.deepcopy(args)
        if args.get("icon"):
            # my current solution
            args["icon"]._id = str(
                hash(tuple([row[geometry_column].y, row[geometry_column].x]))
            )
        folium_object = fl.Marker(
            location=[row[geometry_column].y, row[geometry_column].x], **args
        )
    else:
        folium_object = fl.GeoJson(data=row[geometry_column], **args)
    return folium_object

As you can see Im setting the ID by creating an hash value of the LAT LONs so that I have an unique ID for each icon. Otherwise the map would not work. Can you fix it? So that one icon can be created and used in different markers? Thanks



**Expected behavior**
A clear and concise description of what you expected to happen.

**Environment (please complete the following information):**
 - Browser --> firefox
 - Jupyter Notebook or html files? --> html
 - Python version (check it with `import sys; print(sys.version_info)`) --> sys.version_info(major=3, minor=11, micro=4, releaselevel='final', serial=0)
 - folium version (check it with `import folium; print(folium.__version__)`) --> 0.16.0
 - branca version (check it with `import branca; print(branca.__version__)`) --> 0.7.1
