Double click on "scattergl" plot makes panning option not to work properly

[ifll]

When clicking the panning option of the menubar of the plot it is possible to pan the plot. Once you doubleclick the plot, the panning option is still available but the panning range is rescricted to a small distance, which makes that for covering a large paning you have to click -> pan -> click again -> pan again -> click again....

Clicking again the panning option of the menubar resets the panning and it is available to pan normally again.

It is possible to reproduce this problem here:

@dfcreative might be interested in this issue too ...

That seems to be a CSS issue — some element becomes draggable in some reason.
If we add

.gl-container {
    @include vendor('user-select', none);
}

to _base.scss and rebuild the package, the problem gets fixed, I am not sure though if there are possible use-cases where user may want to actually select something on the plot. For scattergl there is nothing to select, but mb other plot types create some selectable selement in .gl-container.

@dfcreative great. Thanks for looking into this.

The<div gl-container> is used for gl3d and mapbox-gl plots also. So we should make sure that adding that user-select-none class doesn't affect them.

Perhaps we could add the user-select-none class to the gl2d canvas instead to make sure to not affect other plot types.

@dfcreative @etpinard nice solution, thx for referencing URL in the scene2d code!
