P: "Paint bucket tool" doesn't retain selected color when filling...

BUG: CS6: "Paint bucket tool" doesn't retain selected color when filling.

For example, I select this color from the swatches palette...

R 236
G 0
B 140

But when I use the "paint bucket tool" to fill the color into the document, the color in the document is slightly different...

R 237
G 0
B 140

This is easily noticeable when viewing the "info" palette.

I've tried other colors, too.

This happens even if I turn off color management for the document.

No special blending mode is used for tool or layers. I've even reset tools to default settings.

This problem is particular to the "paint bucket tool", and doesn't happen when using the brush and pencil tools.

Can this be fixed?
