1.9.3: Selection sequence of elements in "Enhance colors" window is mixed up

[xytest]

XnView: MP 1.9.3 - 64-bit
OS: Windows 11 - 64-bit

If you navigate through the individual elements in the "Enhance colors" window using the Tab key, not all of them are selected in sequence, but there are unexpected jumps in between.

Effect: You have to press the Tab key more often than necessary to select some elements.

To reproduce:
1. Browse a folder A with an image file (JPEG format).
2. Select the image file.
3. Press Shift-E to open the window "Enhance colors".
4. Click in the field next to "Brightness"
5. Press the Tab key until the field next to "Gamma" is selected
Actual behaviour (bug): You have to press the Tab key 13 times to select the field next to "Gamma" because it is skipped first and only comes later (the order of the elements in this window is generally a bit mixed up, not only in this example).

Expected behaviour: You only have to press the Tab key 4 times to select this field.
