Translucent pixels didn't blend properly over translucent/transparent ones, which manifested in weird results when dragging selections in the icon editor.

This issue has been resolved.
Descriptive Problem Summary:
When you move not fully opaque pixels those pixels will act as if the Mask you use is part of the icon and thus get pasted on the mask and "create" a new color. Also if you select and move something the mask color will change in that selected area to pure black, and stay like this until you exit and reenter the icon state.
https://gyazo.com/6e97336b5e9e765c330f05f5814a42fe I have a bright green mask on and you can see how the transparent-ish pixels change between very dark black and bright green.(the color was originally brown, but that automatically changes to black once you move it, since the mask turns black on the selected area when you start moving)
https://gyazo.com/254675052cf01c85152f4ccbfc0f4f41 Here is how that looks in action, with the RGB+Mask mode.

Numbered Steps to Reproduce Problem:
1. Open a new .dmi file.
2. Draw something which is somewhat transparent.
(2.b not necessary but turn on RGB+mask mode)
3.Select some of those pixels and move them.

Expected Results:
The somewhat transparent pixels not changing color as they are moved.

Actual Results:
The somewhat transparent pixels moveable anywhere without any interference by the mask's color.

Does the problem occur:
Every time? Or how often?
Every time.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked?
It wasn't a problem before the icon editor's overhaul (aka. 512.1455).

Workarounds:
Haven't found any.

Here is a gif. Just moving the translucent parts darkens them. Even if you return them to the origin place, they still stay dark. Undoing gets them back in place but still dark.
