setting a value for 'tool' parameter does not set that tool by default #35

dash_canvas.DashCanvas(
                    id='canvas',
                    width=800,
                    height=445,
                    tool='rectangle',
                    lineWidth=2,
                    filename=filename,
                    hide_buttons=['pencil', 'line', 'pan', 'select', 'zoom'],
                    goButtonTitle='Get coordinates'
                ),

Setting the tool parameter equal to 'rectangle' is supposed to set the tool to rectangle by default when the app is opened, but instead, the 'pan' tool is selected.

Hey @emmanuelle , what's the level of effort on this one? It makes this demo a bit funky: https://dash-demo.plotly.host/annotation-bounding-box/ https://github.com/plotly/dash-customer-success/issues/254#issuecomment-583447075

@jackparmer don't know but probably one or two days to figure out what's going on (maybe less if I get help from Will or Marc-André), plus a new release.

Just to clarify: the code snippet above activates both pan and rectangle behavior for the image loaded into canvas (as shown below in the screencast).

had the same issue with one of my apps. Managed to fix it by installing the previous release of dash pip install dash==1.10.0

Need to figure out why that is...

Hi... Any updates on this issue? I'm still struggling with this problem. If I press the Save button initially, the correct tool gets selected. And nothing shows in the coordinates. But still, this is not good.. :)
