    Issue #3353 - Gimp 2.10.10 freezes while changing Background color ...
    
    ... in LCh colorspace
    
    In gimptoolbox-color-area, when setting the context's background
    color in response to a color-dialog change, block the right signal
    handler, to avoid re-setting the color dialog's color, which would
    cause the GtkAdjustment's "value-changed" signal (assuming it was
    the source of the change) to be restarted if the new value doesn't
    match the current one exactly, which can happen due to conversion
    errors.
