ID 604213 - MC Rollerbrush image colorspace edits do not take effect until Tool Properties > Bitmap settings are edited

Problem summary:

MC Rollerbrush image colorspace edits do not take effect until Tool Properties > Bitmap settings are edited

Steps to reproduce:

1. Create and target an MCP node
2. Load an 8bit image into MCP palette
3. Set the stream with the image as active and view it
4. Paint a stroke
5. In the Image Manager, set the image as scalar
6. Paint another stroke => No change
7. In Tool Properties > Bitmap, make an edit and then reverse it
   E.g. Enable Invert Alpha, then disable it
8. Paint another stroke => Color has now changed

Expected behaviour:

Changing MC roller brush image colorspace should have an instant effect.

Actual behaviour:

Colorspace edits don't have an effect until a change to the Bitmap settings.

Workaround:

No known workaround.
