Color picker changes focus to previous window when you click on "Use"

**To Reproduce (REQUIRED)**
Steps to reproduce the behavior:
1. Open gui scene
2. Select any box node
3. Open color picker
4. Click "Custom color"
5. Click "Use"
6. Previously selected window is opened instead of Defold editor

**Expected behavior (REQUIRED)**
Defold editor is opened

**Defold version (REQUIRED):**
Tested on 1.11.1 and 1.12.0 beta

**Platforms (REQUIRED):**

It is the same problem as described in https://github.com/defold/defold/issues/5823

Reproduce the issue on Windows 10 using the listed GUI scene and color-picker steps, then compare the behavior with issue #5823. Trace the color picker's "Use" action and confirm that completing it leaves focus in the Defold editor rather than opening the previously selected window.
