Short description of error
Using the Bright/Contrast function in Vertex Color mode with only selected faces (pressing M) no changes happen or glitches.

Exact steps for others to reproduce the error

Enter Edit Mode mode on selected mesh object
Select faces
Switch to Vertex Paint mode
Press M to be able to paint only on the selected faces
Go to Paint -> Bright/Contrast
Change the Brightness and Contrast values
Nothing happens. Sometimes it even affects random faces that are not selected.

In this example I try to deepen the brightness of the selected faces a bit:

But nothing happens to the faces. Instead, random vertices of unselected faces get darkened:

Here is the Blender file of the example:

I am also seeing this, but additionally if I turn OFF selected faces, as soon as I start adjusting levels, brightness, contrast, hue, etc. then selected faces gets automatically switched back on. So the buggy behavior described is unavoidable.
