    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.
    
    (cherry picked from commit c7a29e5f98ecb833bf2d87a1df9963a633c6fbe7)
