  [BUG] Dropdown:  Selected options not showing when the `value` contains a comma 
  As [reported on the forum by @ marcus](https://community.plotly.com/t/dcc-dropdown-bug-suspected-please-confirm-or-correct-me/60585):
  
  Problem is in this spot: 'value': "50 , 10"
  Specifically comma in `value` string makes that selection is not being displayed. When coma is removed or replaced (dot creates no issue) it works fine, but when coma is within the string, the selections are not displayed in the input box and are not removed from the `options`
  
   This only occurs in Multi-Value dropdowns.  This is new in Dash V2.1.0  It works as expected in V2.0.0
  
  
  
  
  ```
  from dash import Dash, dcc, html, Input, Output
  
  app = Dash(__name__)
  
  app.layout = html.Div(
      [
          dcc.Dropdown(
              id="dropdown",
              className="inputbox-long",
              options=[
                  {"label": "New York City", "value": "50, 10"},
                  {"label": "Montreal", "value": "MTL" },
                  {"label": "San Francisco", "value": "SF"},
              ],
              placeholder="Select one or more",
              multi=True,
          ),
          html.Div(id="output"),
      ]
  )
  
  
  @app.callback(
      Output("output", "children"), Input("dropdown", "value"),
  )
  def update(value):    
      return value
  
  
  if __name__ == "__main__":
      app.run_server(debug=True)
  ```
