Describe the bug
After adding HistogramConfig in the SetHistogramRequirements and REGION_HISTOGRAM_DATA.
When open an image and request SetHistogramRequirements, there are TWO REGION_HISTOGRAM_DATAs returned. The first REGION_HISTOGRAM_DATA is identical to the REGION_HISTOGRAM_DATA that returned with OpenFileAck.
(If set a region and then request SetHistogramRequirements, there is only ONE REGION_HISTOGRAM_DATA returned, it is what I expected)

To Reproduce
Steps to reproduce the behavior:
0. Open console.log, set "Preference - Log Events" to select All

1. Open "HH211_IQU.fits" (backend <== OPEN_FILE, ==> OPEN_FILE_ACK, ==> REGION_HISTOGRAM_DATA)
2. Click on "Histogram widget"
3. Set Polarization to "Stokes Q"
4. Click top right "setting", and adjust X min to"0"
5. You can see there is ONE request "SET_HISTOGRAM_REQUIREMENTS" but the backend return TWO "REGION_HISTOGRAM_DATA". The first one is identical to Step 1 "REGION_HISTOGRAM_DAT"

Expected behavior
Based on v3, if change the setting in the Histogram widget, there is only ONE "REGION_HISTOGRAM_DAT" returned from the backend
